Herein, we report a facile method for growing CsPbBr 3 cube and prism microcrystals by microspacing in-air sublimation. Morphology-dependent photoluminescence behavior investigation reveals that the CsPbBr 3 cubes show higher photoluminescence quantum yield and longer PL lifetime than the prisms. In contrast, CsPbBr 3 prisms exhibit more considerable light-induced photoluminescence enhancement.
