Abstract

Herein, we report a facile method for growing CsPbBr₃ cube and prism microcrystals by microspacing in-air sublimation. Morphology-dependent photoluminescence behavior investigation reveals that the CsPbBr₃ cubes show higher photoluminescence quantum yield and longer PL lifetime than the prisms. In contrast, CsPbBr₃ prisms exhibit more considerable light-induced photoluminescence enhancement.
