Abstract

CsPbBr₃ nanocrystals (NCs) are successfully prepared by using SrBr₂ salt as a growth medium in a melt crystallization process. The obtained CsPbBr₃ NCs exhibit a photoluminescence peak of 524 nm with a narrow emission linewidth of 25 nm, which can offer a wide color gamut display. This study can be extended to other alkali metal and alkali earth metal halides and may become a general method for the synthesis of perovskite NCs.
