Property of CsPbBr3 Perovskite Nanocrystals Prepared in Different Solvents
All inorganic perovskite nanocrystals have broad application prospects in functional optical materials and optical devices due to their high quantum yield
narrow line width and full band visible light emission characteristics. The effect of solvent density
polarity and viscosity on the reaction process
crystal structure
microstructure and optical properties of CsPbBr

perovskite nanocrystals was studied in this work. The results show that the growth of CsPbBr
3
perovskite nanocrystals in the upper
lower and whole liquid phase of the reactor can be realized by changing the density of the reaction solvent. The higher the polarity of the solvent
the lower the crystallinity
the lower the luminescence intensity and stability. High solvent viscosity is not conducive to the preparation of high quality CsPbBr

perovskite nanocrystals. The method proposed in this paper is expected to further improve its application in solar cells
