Abstract

As a direct bandgap semiconductor, organic-inorganic lead halide perovskite (MAPbX₃, MA = CH₃NH₃, X = Cl, Br, I) have been considered as promising materials for laser due to their excellent optoelectronic properties. The perovskite materials with 1D and 2D shapes were widely prepared and studied for Fabry-Pérot mode and whispering-gallery-mode (WGM) microcavities, but cuboid-shape is rarely reported. In this work, we successfully fabricated single crystal cuboid-shaped MAPbBr₃ perovskite with different morphologies, named microcuboid-MAPbBr₃ (M-MAPbBr₃) and multi-step-MAPbBr₃ (MS-MAPbBr₃), via solvothermal method. Furthermore, the as-prepared crystals' excitonic recombination lifetime under different pumping energy density was studied by time-resolved photoluminescence (TRPL). Based on controllable morphology and remarkable lasing properties, these cuboid shaped single crystal perovskite could be a promising candidate for small laser, and other optoelectronic devices.
