Abstract

Due to their high absorption efficiency, great carrier diffusion length, and low surface recombination velocity, lead halide perovskite micro- and nano-lasers have been extensively studied for their potential applications in optoelectronic devices and photonics integration. But it is still a challenge to achieve a stable and controllable lasing action, especially for single-mode lasing. Herein, solution-processed single-crystal CH3NH3PbBr3 perovskite microsheets and microwires were synthesized to realize Fabry–Pérot lasing at room temperature. Based on their high crystalline quality and high optical confinement, the lasing actions were investigated systematically. The lasing mode regulation was carried out from multiple modes to the single mode via reducing the width of CH3NH3PbBr3 microstructures.
