However, the poor stability as the results of the high sensitivity to heat and moisture limits their further applications. Here, we report a facile one-pot approach to synthesize $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs at room temperature. Due to the effective defects passivation using $\\\\mathbf{sio}_{2}$ , as-prepared $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs present an enhanced photoluminescence quantum yield (PLQY) and chemical stability. The PLQY of $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs reaches $71.6\\\\%$ which is higher than $46\\\\%$ in pure $\\\\mathbf{CsPbBr}_{3}$ QDs. The PL intensity of $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs maintains $\\\\mathbf{84\\\\%}$ while remaining $\\\\pm{24\\\\%}$ in pure $\\\\mathbf{CsPbBr}_{3}$ after ${\\\\bf80\\\\ m i n}$ heating at $60^{\\\\circ}\\\\mathbf{C}$ . The ASE performance of the films is also studied under a two-photonpumped laser. Compared with the films using pure $\\\\mathbf{CsPbBr}_{3}$ QDs, those with as-prepared $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs exhibit a reduced threshold of ASE. The work suggests that room-temperature-synthesized $\\\\mathbf{SiO}_{2}$ -coated perovskites QDs are promising candidates for laser devices. $\\\\circledcirc$ 2020 Chinese Laser Press \\n\\nhttps://doi.org/10.1364/PRJ.399845', 'metadata': None, 'embedding': None, 'score': None}, {'id': None, 'title': 'Water-Assisted Size and Shape Control of CsPbBr3 Perovskite Nanocrystals.md', 'content': '\\n\\nWater-Assisted Size and Shape Control of CsPbBr3 Perovskite Nanocrystals\\nXiaoyu Zhang, Xue Bai,\\\\* Hua Wu, Xiangtong Zhang, Chun Sun, Yu Zhang, Wei Zhang, Weitao Zheng,\\\\* William W.

Oleylamine (OLA, $80{-}90\\\\%$ ), $\\\\mathrm{K_{n}N a_{12-n}[(A l O_{2})_{12}(S i O_{2})_{12}]\\\\cdot x H_{2}O}$ (molecular sieves, 3 \u00c5), CsBr $(99.9\\\\%)$ , and $\\\\mathrm{PbBr}_{2}$ $(99.0\\\\%)$ were purchased from Aladdin. Dimethylformamide (DMF, $99.8\\\\%$ ) was obtained from Sigma-Aldrich. \\n\\nSynthesis of CsPbBr3 NCs. As illustrated in Figure S1, the synthesis of CsPbBr3 NCs was carried out at room temperature by LARP approach, through injection of 1 mL of precursor mixture (which we denote by a generic term \u201cprecursor\u201d further on) into a \u201cbad solvent\u201d toluene ( $10\\\\,\\\\mathrm{\\\\mL})$ ) under vigorous stirring (Figure S1b). The precursor was prepared by mixing CsBr $\\\\left(0.4\\\\mathrm{\\\\mmol}\\\\right)$ ), $\\\\mathrm{PbBr}_{2}$ $\\\\left(0.4\\\\mathrm{\\\\mmol}\\\\right)$ , oleylamine (OLA, $0.5\\\\;\\\\mathrm{mL}$ ), and oleic acid (OA, $1\\\\ \\\\mathrm{mL}$ ) in a \u201cgood solvent\u201d DMF ( $\\\\mathrm{\\\\Delta^{10}\\\\,m L}$ ) (Figure S1a). Both the solvents DMF and toluene have been dried from any remaining traces of water prior to use (DMF by adding $\\\\mathrm{K_{n}N a_{12-n}[(A l O_{2})_{12}(S i O_{2})_{12}]}$ , and toluene via distillation). When investigating the influence of water added to the \u201cbad solvent\u201d, 1 mL of the dry precursor was injected into a mixture of toluene and water $\\\\ 10\\\\ \\\\mathrm{mL}+x\\\\quad$ \u03bcL, $0{\\\\le}x{\\\\le}60)$ ) (Figure S1c). When investigating the influence of water added to the precursor, $1\\\\,\\\\textrm{m L}$ solution taken from the mixture of $1~\\\\mathrm{mL}$ dry precursor and $x\\\\ \\\\upmu\\\\mathrm{L}$ $(0{\\\\le}x{\\\\le}60)$ water was injected into dry toluene (Figure S1d). \\n\\n![](https://imgbed.siat-mic.com/i/2024/08/29/ceb29ded5d4667ca241bfa24beea7406570a26c119bea2e00127f333213eb98c-1724930950.jpg) \\nFigure S1. The synthesis of CsPbBr3 NCs using trace amounts of water, carried out by LARP approach. See text for details. \\n\\nDevice Fabrication. Patterned ITO-coated glass was carefully cleaned successively using soap, deionized water, ethanol, chloroform, acetone, and isopropanol, and was subjected to UV-ozone treatment for $15\\\\;\\\\mathrm{min}$ . A solution of ZnO NCs was spin-coated onto the ITO glass at $1000\\\\ \\\\mathrm{rpm}$ for 1 min and annealed in air at $150~^{\\\\circ}\\\\mathrm{C}$ for $10\\\\ \\\\mathrm{min}$ . The CsPbBr3 NC active layers were spin-cast at 1000 rpm for 1 min. 4,4\\',4\"-tris(carbazol-9-yl)-triphenylamine (TCTA), $\\\\mathbf{MoO}_{3}$ , and Au films were sequentially deposited by thermal evaporation in a vacuum deposition clamber $\\\\lfloor1\\\\times$ $10^{-7}$ Torr). \\n\\nCharacterization. Absorption and photoluminescence (PL) spectra were measured on a PerkinElmer Lambda 950 spectrometer and a Cary Eclipse spectrofluorimeter, respectively. Transmission electron microscopy (TEM) images were obtained on a FEI Tecnai F20 microscope. Powder XRD data were collected on a Bruker SMART-CCD diffractometer. Fourier transform infrared spectroscopy (FTIR) was performed on an IFS-66V/S FTIR spectrophotometer. The absolute PL QYs of the samples were measured on a fluorescence spectrometer (FLS920P, Edinburgh Instruments) equipped with an integrating sphere with its inner face coated with BENFLEC. Time-resolved PL measurements were performed with a time correlated single-photon counting (TCSPC) system of the FLS920P Edinburgh spectrometer. A 379 nm picosecond diode laser (EPL-375, repetition rate 5 MHz, 64.8 ps) was used to excite the samples. Ultraviolet photoelectron spectroscopy (UPS) spectra were collected on a PREVAC system. A Keithley 2612B source meter was used to measure the current\u2212voltage characteristics of the devices. The light output was measured by a calibrated Newport 1936-R power meter with a 918D-SL-0D3R silicon photodetector positioned at a fixed distance and directed toward the ITO glass side of the device. The LED brightness was determined from the fraction of light that reached the photodetector. The EL spectra were recorded on a Maya spectrometer (Ocean Optics) coupled to an optical fiber. \\n\\n![](https://imgbed.siat-mic.com/i/2024/08/29/1169be28aaba38f450b8bce24f52cfc427ad5ee68fee3c54cc3e0969302582d0-1724930949.jpg) \\nFigure S2. (a) A TEM image of two large-sized spherical perovskite particles synthesized without water additive. (b) Elemental mapping of a perovskite particle, indicating that Cs, Pb, and Br atoms are uniformly incorporated. \\n\\nWe further demonstrate how smaller perovskite NCs serve as seeds for bigger particles by extending the growth time of $0~\\\\upmu\\\\mathrm{L}$ samples to 2 weeks. Large spherical particles with diameters over $100\\\\ \\\\mathrm{nm}$ can be observed in the corresponding TEM image (Figure S2a). In order to confirm their chemical composition, we used elemental mapping, with data showing that Cs, Pb, and Br elements were uniformly distributed over the particle volume (Figure S2b). We note that the large particles (exceeding $100\\\\,\\\\textrm{n m}$ in size) obtained in waterless conditions were amorphous or poorly crystallized and exhibited quasi-spherical shapes, while those synthesized in the presence of water were crystalline and exhibited square-like shape, which shows that traces of water influence the CsPbBr3 NC crystallization in a significant extent. \\n\\n![](https://imgbed.siat-mic.com/i/2024/08/29/4d11d43a8d1581ab2b32e90027f914ba421136ffad499479cb345e34d412a5c9-1724930952.jpg) \\nFigure S3. (a) UV-Vis absorption and (b) PL spectra of $\\\\mathrm{Cs}{\\\\mathrm{Pb}}{\\\\mathrm{Br}}_{3}$ NCs synthesized using dry DMF and different amount of methanol added into toluene, as indicated on the frames. \\n\\nFrom the above discussed results, we conclude that water traces help to form crystalline (orthorhombic phase) of CsPbBr3 NCs. It is plausible to assume that other polar solvents may also induce the same trend. Indeed, upon addition of traces of dry methanol (another polar solvent) into toluene, a similar phenomenon has been observed: along with increasing amount of methanol added, both the absorption and emission spectra of CsPbBr3 NCs experienced a gradual red-shift (Figure S3). \\n\\n![](https://imgbed.siat-mic.com/i/2024/08/29/9007b56cfc090d6bebdfb2cb9da2a703ea1d18aef64ab40016a8801bbd651565-1724930948.jpg) \\n\\nFigure S4. (a) PL spectra of $\\\\mathrm{Cs}\\\\mathrm{Pb}{\\\\mathrm{Br}}_{3}$ NC solution and the respective LED, and the EL spectrum of the LED. Inset shows the UPS spectra of $30~\\\\upmu\\\\mathrm{L}$ CsPbBr3 NC film deposited on ITO glass substrate. (b) The energy band diagram of an inverted LED structure. The CsPbBr3 NC energy bands were determined from UPS, while others are taken from ref [1]. (c) Current density and brightness of the LED vs. the driving voltage. A photograph of the operating device is given as an inset. (d) Current efficiency and EQE of the CsPbBr3 NC based LED vs. luminance. \\n\\nAs shown in Figure S4a, the PL peak of NC solution was located at $511~\\\\mathrm{nm}$ , and a red-shift of $7\\\\ \\\\mathrm{nm}$ was observed for the PL peak of the respective devices, which originates from the energy transfer from smaller to larger NCs in the ensemble and/or from the change of the dielectric function of the surrounding medium. An inverted hybrid inorganic/organic LED design was employed as the device architecture. The \\n\\nNCs\u2019 valence band maximum and conduction band minimum were determined via the ultraviolet photoelectron spectroscopy (UPS, Figure S4a). The device emission peak at $E=2.39\\\\ \\\\mathrm{eV}$ ( $518\\\\ \\\\mathrm{nm}$ ) was taken as the optical bandgap. Figure S4b shows the flat-band energy level diagram of the LED. By carefully choosing the charge-transport layer and optimizing the thickness of each layer, both charge transport and injection balance have been achieved. A bright EL from $\\\\mathrm{Cs}\\\\mathrm{Pb}{\\\\mathrm{Br}}_{3}$ NCs peaked at $518~\\\\mathrm{nm}$ was observed, which matched the device PL spectrum except for a marginal $\\\\,2\\\\ \\\\mathrm{nm})$ increase in the full width at half maximum. The peak luminance of 4428 cd $\\\\mathrm{m}^{-2}$ was detected at $10.5\\\\mathrm{~V~}$ ( $208\\\\ \\\\mathrm{mA\\\\cm^{-2}}$ ) (Figure S4c), while the device efficiency of the peak values of current efficiency of 5.8 cd $\\\\mathbf{A}^{-1}$ and external quantum efficiency (EQE) of $1.7\\\\%$ were achieved (Figure S4d). The peak EQE was enhanced 28 and 4.2 times compared to that of our previously reported CsPbBr3 NC LEDs.[1, 3] \\n\\nTable S1.

The main chemical reagents including cesium bromide (CsBr, Aladin, $99.9\\\\%$ ), lead bromide (PbBr2, Aladin, $99.0\\\\%$ ), N,N-dimethylformamide (DMF, Aladin, $99.9\\\\%$ ), oleylamine (OAm, Aladin, $\\\\mathrm{C}18{:}80{-}90\\\\%$ ), oleic acid (OA, Aladdin, AR), 1H,1H,2H,2H-Perfluorodecyltrichlorosilane (FDTS, Aladin, $96\\\\%$ ), chloroform (Sinopharm, $99.0\\\\%$ ), ethonal (Sinopharm, $99.8\\\\%$ ), acetone (Sinopharm, $99.0\\\\%$ ), gold (Zhongnuo Advanced Material (Beijing) Technology Co., Ltd, $99.99\\\\%$ ) were used without purification, except chloroform which was dehydrated before use. \\n\\nSynthesis of purified CsPbBr3 NCs. The CsPbBr3 NCs were prepared by the ligandassisted reprecipitation method. Firstly, CsBr (0.4 mmol), $\\\\mathrm{PbBr}_{2}$ ( $\\\\leftmoon.4\\\\mathrm{\\\\mmol}\\\\right)$ ) were dissolved in DMF $\\\\mathrm{[0\\\\,mL]}$ ). Subsequently, OAm $\\\\left(0.1\\\\,\\\\mathrm{mL}\\\\right)$ ) and OA (1 mL) were added to stabilize the precursor solution until the powder was completely dissolved. 1 mL of the precursor solution was added quickly into chloroform ( $\\\\mathrm{[0\\\\mL]}$ under vigorous stirring, and strong green emission was observed immediately. After three times centrifugation ( $10{,}000\\\\;\\\\mathrm{rpm}$ , $10\\\\;\\\\mathrm{min}$ ), purified CsPbBr3 NCs can be obtained. \\n\\nSynthesis of CsPbBr3 $@$ FDTS NCs. The FDTS dispersant should be freshly prepared before use ( $10\\\\;\\\\mathrm{mL}$ chloroform, $30~\\\\upmu\\\\mathrm{L}$ ethanol, $1.5~\\\\upmu\\\\mathrm{L}$ deionized water and 10 $\\\\upmu\\\\mathrm{L}$ FDTS). Then $1~\\\\mathrm{mL}$ chloroform and $1~\\\\mathrm{mL}$ FDTS dispersant were added into the redispersed purified CsPbBr3 NCs chloroform solution ( $2\\\\,\\\\mathrm{mL})$ in sequence with a 5 min interval. After stirring for 10 min, $1~\\\\mathrm{mL}$ chloroform and $1~\\\\mathrm{mL}$ FDTS dispersant were added again. The obtained colloid solution was centrifugated (10,000 rpm, 10 min) to get the CsPbBr3@FDTS NCs, which were used for the TEM characterization (Figure \\n\\n1c) and photodetector fabrication. After further drying at $50\\\\,^{\\\\circ}\\\\mathrm{C}$ , the CsPbBr3 $@$ FDTS powders were used for other material characterizations and stability tests. \\n\\nPreparation of the CsPbBr3 $@$ FDTS flexible photodetector. The CsPbBr3@FDTS NCs were redispersed in chloroform to form a $10\\\\,\\\\mathrm{g/mL}$ uniform dispersion. Polyimide (PI) membranes $2.5\\\\ \\\\mathrm{cm}\\\\times2.5\\\\ \\\\mathrm{cm}$ ) were cleaned sequentially in acetone, ethanol and deionized water. The CsPbBr3@FDTS film was obtained by the drop-casting method, and then the gold electrodes $\\\\mathrm{\\\\Delta}1\\\\ \\\\mathrm{mm}\\\\times1\\\\ \\\\mathrm{mm}$ ) were deposited on the composite film by thermal evaporation, and the channel length between the Au electrodes is $25\\\\;\\\\upmu\\\\mathrm{m}$ . \\n\\n**Characterization**\\n\\nThe morphology of nanocrystals was examined by transmission electron microscopy (TEM, FEI Talos F200X) at $200~\\\\mathrm{kV}.$ The composition was determined by energydispersive X-ray spectroscopy (EDS) using the accessory manufactured by Oxford instruments. To characterize the structure, powder X-ray diffraction (XRD) was performed on a Rigaku Smartlab 3kW X-ray diffractometer with $\\\\mathrm{{Cu\\\\K_{\\\\alpha}}}$ radiation $\\\\uplambda=$ 1.54056 \u00c5, 40 kV, $30~\\\\mathrm{~mA}$ , $10^{\\\\circ}\\\\:\\\\mathrm{\\\\min}^{-1}$ from 10 to $60^{\\\\circ}$ ). X-ray photoelectron spectroscopy (XPS) was carried out on the Thermo ESCALAB 250Xi system. The structure of the composites was analyzed by Fourier transform infrared spectroscopy (FTIR, Thermo Scientific, Nicolet iS60) with the KBr pellet method. The PL and TRPL properties were determined using a fluorescent spectrophotometer (Hitachi F4600 and Edinburgh FLS-1000) at an excitation wavelength of $365~\\\\mathrm{\\\\Omeganm}$ . The absorption spectra were obtained on the Lambda25 UV-Vis-NIR spectrophotometer. The morphology of the perovskite films was examined by scanning electron microscopy (SEM, Zeiss GeminiSEM 300) and atomic force microscopy (AFM, Bruker, USA). The mechanical properties such as elastic modulus and hardness were detected by a Nanoindenter XP (Bruker Hysitron TI950).

ID 399845); published 22 September 2020 \\n\\nAll-inorganic cesium lead bromide $({\\\\bf C}{\\\\bf s}{\\\\bf P}{\\\\bf b}{\\\\bf B}{\\\\bf r}_{3})$ ) perovskite quantum dots (QDs) with excellent optical properties have been regarded as good gain materials for amplified spontaneous emission (ASE). However, the poor stability as the results of the high sensitivity to heat and moisture limits their further applications. Here, we report a facile one-pot approach to synthesize $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs at room temperature. Due to the effective defects passivation using $\\\\mathbf{sio}_{2}$ , as-prepared $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs present an enhanced photoluminescence quantum yield (PLQY) and chemical stability. The PLQY of $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs reaches $71.6\\\\%$ which is higher than $46\\\\%$ in pure $\\\\mathbf{CsPbBr}_{3}$ QDs. The PL intensity of $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs maintains $\\\\mathbf{84\\\\%}$ while remaining $\\\\pm{24\\\\%}$ in pure $\\\\mathbf{CsPbBr}_{3}$ after ${\\\\bf80\\\\ m i n}$ heating at $60^{\\\\circ}\\\\mathbf{C}$ . The ASE performance of the films is also studied under a two-photonpumped laser. Compared with the films using pure $\\\\mathbf{CsPbBr}_{3}$ QDs, those with as-prepared $\\\\mathbf{CsPbBr}_{3}@\\\\mathbf{SiO}_{2}$ QDs exhibit a reduced threshold of ASE. The work suggests that room-temperature-synthesized $\\\\mathbf{SiO}_{2}$ -coated perovskites QDs are promising candidates for laser devices. $\\\\circledcirc$ 2020 Chinese Laser Press \\n\\nhttps://doi.org/10.1364/PRJ.399845', 'metadata': None, 'embedding': None, 'score': None}, {'id': None, 'title': 'Flexible All-Inorganic Perovskite Photodetector with a Combined Soft-Hard Layer Produced.md', 'content': 'Supporting Information\\n**Flexible All-Inorganic Perovskite Photodetector with a Combined Soft-Hard Layer Produced by Ligand Cross-Linking**\\n\\nTongyu Shi1,2, Xi Chen1,2, Rui He1\\\\*, Hao Huang1, Xinru Yuan1,2, Zhenyu Zhang1, Jiahong Wang $I,2,3$ , Paul K. Chu4, Xue-Feng Yu1,2,3\\\\* \\n\\n**METHOD**\\n\\nMaterials. The main chemical reagents including cesium bromide (CsBr, Aladin, $99.9\\\\%$ ), lead bromide (PbBr2, Aladin, $99.0\\\\%$ ), N,N-dimethylformamide (DMF, Aladin, $99.9\\\\%$ ), oleylamine (OAm, Aladin, $\\\\mathrm{C}18{:}80{-}90\\\\%$ ), oleic acid (OA, Aladdin, AR), 1H,1H,2H,2H-Perfluorodecyltrichlorosilane (FDTS, Aladin, $96\\\\%$ ), chloroform (Sinopharm, $99.0\\\\%$ ), ethonal (Sinopharm, $99.8\\\\%$ ), acetone (Sinopharm, $99.0\\\\%$ ), gold (Zhongnuo Advanced Material (Beijing) Technology Co., Ltd, $99.99\\\\%$ ) were used without purification, except chloroform which was dehydrated before use. \\n\\nSynthesis of purified CsPbBr3 NCs. The CsPbBr3 NCs were prepared by the ligandassisted reprecipitation method. Firstly, CsBr (0.4 mmol), $\\\\mathrm{PbBr}_{2}$ ( $\\\\leftmoon.4\\\\mathrm{\\\\mmol}\\\\right)$ ) were dissolved in DMF $\\\\mathrm{[0\\\\,mL]}$ ). Subsequently, OAm $\\\\left(0.1\\\\,\\\\mathrm{mL}\\\\right)$ ) and OA (1 mL) were added to stabilize the precursor solution until the powder was completely dissolved. 1 mL of the precursor solution was added quickly into chloroform ( $\\\\mathrm{[0\\\\mL]}$ under vigorous stirring, and strong green emission was observed immediately. After three times centrifugation ( $10{,}000\\\\;\\\\mathrm{rpm}$ , $10\\\\;\\\\mathrm{min}$ ), purified CsPbBr3 NCs can be obtained. \\n\\nSynthesis of CsPbBr3 $@$ FDTS NCs. The FDTS dispersant should be freshly prepared before use ( $10\\\\;\\\\mathrm{mL}$ chloroform, $30~\\\\upmu\\\\mathrm{L}$ ethanol, $1.5~\\\\upmu\\\\mathrm{L}$ deionized water and 10 $\\\\upmu\\\\mathrm{L}$ FDTS). Then $1~\\\\mathrm{mL}$ chloroform and $1~\\\\mathrm{mL}$ FDTS dispersant were added into the redispersed purified CsPbBr3 NCs chloroform solution ( $2\\\\,\\\\mathrm{mL})$ in sequence with a 5 min interval. After stirring for 10 min, $1~\\\\mathrm{mL}$ chloroform and $1~\\\\mathrm{mL}$ FDTS dispersant were added again. The obtained colloid solution was centrifugated (10,000 rpm, 10 min) to get the CsPbBr3@FDTS NCs, which were used for the TEM characterization (Figure \\n\\n1c) and photodetector fabrication. After further drying at $50\\\\,^{\\\\circ}\\\\mathrm{C}$ , the CsPbBr3 $@$ FDTS powders were used for other material characterizations and stability tests. \\n\\nPreparation of the CsPbBr3 $@$ FDTS flexible photodetector. The CsPbBr3@FDTS NCs were redispersed in chloroform to form a $10\\\\,\\\\mathrm{g/mL}$ uniform dispersion. Polyimide (PI) membranes $2.5\\\\ \\\\mathrm{cm}\\\\times2.5\\\\ \\\\mathrm{cm}$ ) were cleaned sequentially in acetone, ethanol and deionized water. The CsPbBr3@FDTS film was obtained by the drop-casting method, and then the gold electrodes $\\\\mathrm{\\\\Delta}1\\\\ \\\\mathrm{mm}\\\\times1\\\\ \\\\mathrm{mm}$ ) were deposited on the composite film by thermal evaporation, and the channel length between the Au electrodes is $25\\\\;\\\\upmu\\\\mathrm{m}$ . \\n\\n**Characterization**\\n\\nThe morphology of nanocrystals was examined by transmission electron microscopy (TEM, FEI Talos F200X) at $200~\\\\mathrm{kV}.$ The composition was determined by energydispersive X-ray spectroscopy (EDS) using the accessory manufactured by Oxford instruments. To characterize the structure, powder X-ray diffraction (XRD) was performed on a Rigaku Smartlab 3kW X-ray diffractometer with $\\\\mathrm{{Cu\\\\K_{\\\\alpha}}}$ radiation $\\\\uplambda=$ 1.54056 \u00c5, 40 kV, $30~\\\\mathrm{~mA}$ , $10^{\\\\circ}\\\\:\\\\mathrm{\\\\min}^{-1}$ from 10 to $60^{\\\\circ}$ ). X-ray photoelectron spectroscopy (XPS) was carried out on the Thermo ESCALAB 250Xi system. The structure of the composites was analyzed by Fourier transform infrared spectroscopy (FTIR, Thermo Scientific, Nicolet iS60) with the KBr pellet method. The PL and TRPL properties were determined using a fluorescent spectrophotometer (Hitachi F4600 and Edinburgh FLS-1000) at an excitation wavelength of $365~\\\\mathrm{\\\\Omeganm}$ . The absorption spectra were obtained on the Lambda25 UV-Vis-NIR spectrophotometer. The morphology of the perovskite films was examined by scanning electron microscopy (SEM, Zeiss GeminiSEM 300) and atomic force microscopy (AFM, Bruker, USA). The mechanical properties such as elastic modulus and hardness were detected by a Nanoindenter XP (Bruker Hysitron TI950). Electric and optoelectronic measurements of the fabricated devices were conducted in darkness and recorded by the PDA FS380 semiconductor analyzer. \\n\\n![](https://imgbed.siat-mic.com/i/2024/08/29/ecff7f895eefd301189f0cd539cf86b3c21ca18096307a0f6ac124cbd21b8b57-1724930511.jpg) \\n\\nFigure S1.

Conclusion\\nIn summary, in this work, we report a facile SR method for the synthesis of highly emissive IPQDs. Emissions covering the entire visible region can be obtained via f ine controlling of composition and particle size. Excellent photoluminescence with narrow line-widths, high QY up to ${\\\\approx}90\\\\%$ and high photo stability are achieved, which are comparable with that synthesized by HI method. Detailed investigations about the inf luences of surface states and crystal structures on optical properties were made. The exciton binding energies are calculated to be 40 and $44~\\\\mathrm{meV}$ for CPB-M and CPB-C, which are appropriate for the stimulated emission at RT. The Br rich surface states endow $\\\\mathrm{Cs}\\\\mathrm{Pb}{\\\\mathrm{Br}}_{3}$ QDs with interesting anion exchange reactions, selfpassivating, and self-soldering behaviors. Finally, thanks to the outstanding optical properties, WLED with pure white color and high stability are fabricated. There is no doubt that this eff icient approach for the synthesis of the outstanding QDs will be in favor of a range of applications including lasing, lighting, and display. Though more investigations are needed to reveal the correlations between structural (especially the surface states) and physical properties, our f indings will provide good references and enhance researchers\u2019 understanding of this QD system, pushing it to a new research paradigm in the f ield of optoelectronic devices, as well as sensors and memristors. \\n\\npurif ication. In a typical synthesis of $\\\\mathsf{C s P b B r}_{3}$ , $\\\\mathsf{P b B r}_{2}$ $(0.4\\\\,\\\\mathsf{\\\\,m m o l})$ and CsBr $(0.4\\\\,\\\\mathsf{\\\\,m m o l})$ were dissolved in DMF or DMSO $(10\\\\ m L)$ . OA $(1\\\\ m L)$ and $\\\\mathsf{O A m}$ $(0.5\\\\;\\\\mathrm{\\\\mL})$ were added to stabilize the precursor solution. Then, $\\\\rceil\\\\mathsf{\\\\Omega}_{\\\\mathsf{m L}}$ of the precursor solution was quickly added into toluene $(\\\\mathsf{10\\\\ m L})$ under vigorous stirring. Strong green emission was observed immediately after the injection. Other samples with different colors were fabricated with the mixture of $\\\\mathsf{P b X}_{2}$ and $\\\\mathsf{C s X}$ $(\\\\mathsf{X}=\\\\mathsf{C}\\\\mathsf{I}$ , Br, I). All above operations were implemented at room temperature, which varies with seasons from about $30^{\\\\circ}$ in the summer of Nanjing to about $0^{\\\\circ}$ in the winter of Najing. \\n\\nSynthesis of $\\\\mathsf{C s}P b X_{3}$ QDs with $H I$ Method : First, the Cs-precursor was prepared according to our previous report and stored in a glove-box before use. In a typical synthesis of $\\\\mathsf{C s P b B r}_{3}$ , octadecene ( $.75m L$ , ODE), OA $(1.5\\\\ m L)$ , OAm $(1.5\\\\ m L)$ , and $\\\\mathsf{P b B r}_{2}~(0.2~\\\\mathsf{g})$ were mixed and degased under argon for $\\\\intercal\\\\ {\\\\mathsf{h}}$ . To obtain cubic structure, the reaction temperature was raised up to $180\\\\ ^{\\\\circ}C$ and the system was kept at this temperature for more $20\\\\,\\\\mathsf{m i n}$ . After that, $\\\\mathsf{\\\\tau}_{\\\\mathsf{m L}}$ of the Cs-precursor was swiftly injected into above system and the reaction was stopped immediately with ice bath. The IPQDs were washed with acetone and toluene via precipitation and redispersed in toluene f inally. When injecting Cs precursor below $740\\\\ ^{\\\\circ}\\\\mathsf C_{\\\\mathrm{r}}$ monoclinic structure was obtained. Other samples with different colors were fabricated with the mixture of $\\\\mathsf{P b X}_{2}$ $(\\\\mathsf X=\\\\mathsf C|$ , Br, I). \\n\\nFabrication of LED Devices : IPQDs/PMMA composites were prepared via dispersing the colloids into the PMMA/chloroform solution. Then, composite layers were casting onto the surface of a blue LED chips (centered at $460\\\\ \\\\mathsf{n m}$ ) and dried under vacuum at $60~^{\\\\circ}\\\\mathrm{C}$ for $72~\\\\mathsf{h}$ \\n\\nMeasurement and Characterization : XRD patterns were recorded on a multipurpose XRD system D8 Advance from Bruker. UV/Vis absorption spectra were obtained using a Shimadzu 3600 UV/Vis spectrophotometer and photoluminescence spectra were measured with a Varian Cary Eclipse instrument. SEM images and EDX results were measured on FEI Quanta 250F. HRTEM images were recorded on FEI Tecnai G20. Fluorescence lifetimes were measured using a Horiba FM-4P time-corrected single-photon-counting (TCSPC) system. The temperature dependent photoluminescence spectra were measured at Horiba luminescence spectrometer (HR 320) with a laser excitation $(442\\\\,\\\\mathsf{\\\\ n m})$ at different temperatures in a closed-circuit liquid helium system. The light source was focused onto the sample substrate by an immersion-oil objective and the PL signal of single-particle was collected by the same objective and a charge-coupled device camera. Meanwhile, the PL signal was sent through a beam splitter tube to two avalanche photodiodes in a Hanbury Brown-Twiss conf iguration for the PL decay measurement. The QYs of the samples were measured according to our previous reports. The reference dyes are quinine sulfate, f luorescein and rhodamine 6G. \\n\\nComputational Details : All the density functional calculations are performed by using the Vienna ab simulation package (VASP),[ 45 ] under periodic boundary conditions. The projector-augmented-wave (PAW) potential with cesium (Cs), lead $(\\\\mathsf{P b})$ , and bromine (Br) is described as valence. Spin-orbital coupling (SOC) effect is induced because of Cs and Pb element. Geometry optimization and band structure calculations are carried out under the Perdew, Burke, and Ernzerholf (PBE)[ 46 ] exchange-correlation functional. The kinetic energy cutoff of the plane wave is set to be $500~{\\\\mathsf{e V}}$ on a grid of $11\\\\times11\\\\times11$ k-points. The accuracy can be verif ied by the optimized $\\\\mathsf{C s P b B r}_{3}$ lattice parameter a = 5.99 \u00c5.[ 18 ] \\n\\nSynthesis of $C s P b X_{3}$ QDs with SR Strategy : All the reagents were purchased from Aladdin and were used directly without further', 'metadata': None, 'embedding': None, 'score': None}]", "call_id": "call_QvD9lp53ZRUZH95MopgzbWVz"}], "type": "ToolCallExecutionEvent"}, {"source": "Scientist_SynthesisAgent", "models_usage": {"prompt_tokens": 7562, "completion_tokens": 1232}, "content": "Let's analyze the retrieved knowledge for synthesizing CsPbBr3 nanocubes at room temperature to create a robust and detailed synthesis scheme:\n\n---\n\n### Analysis of Knowledge Fragments:\n\n**Fragment 1:**\n1.

In liquid exfoliation, the bulk layered material is dispersed in a liquid medium, where its weak van der Waals forces holding the layers together can be overcome. This is achieved through several methods: oxidation, which modifies the material chemically; ion intercalation or exchange, where ions are inserted between the layers to increase spacing; and surface passivation by solvents, which helps to weaken the interlayer attractions. The combination of these methods allows the layered crystals to be delaminated into high-aspect ratio nanosheets with a large surface area, making them suitable for creating thin films, composites, and other advanced materials.' +""" +print(data) \ No newline at end of file
