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. [ABSTRACT FROM AUTHOR]
