Study on phase regulation in quasi-2D perovskite light-emitting diodes
Metal halide perovskites have garnered significant attention in the field of optoelectronics due to their excellent optoelectronic properties and ease of fabrication,positioning them as revolutionary new optoelectronic semiconductor materials with vast application prospects.Among these materials,quasi-2D perovskites have tunable optophysical properties,including higher exciton binding energy,multiple-quantum well structures,inherent energy funneling,and bandgaptunability,making them promising candidates for next-generation light-emitting diodes(LED).Precise control over the phase distribution of quasi-2D perovskites is paramount for achieving high-efficiency perovskite LED.Based on our group's research work,the strategies of realizing efficient quasi-2D perovskite LED by precisely regulating phase distribution are discussed.
