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.

通过在卤化物盐中熔融结晶来合成卤化钙钛矿型纳米晶。

通过在熔融结晶过程中使用SrBr ₂盐作为生长介质成功地制备了CsPbBr ₃纳米晶体（NCs）。所获得的CsPbBr ₃ NC表现出524 nm的光致发光峰和25 nm的窄发射线宽，可提供较宽的色域显示。这项研究可以扩展到其他碱金属和碱土金属卤化物，并可能成为合成钙钛矿NCs的通用方法。
