Inhibiting thermal quenching of high-efficiency quasi-2D perovskite LEDs
Metal halide perovskites are characterized by low-cost, high photoluminescence quantum yield, and high color purity. In recent years, perovskite light-emitting diodes are developing fast, with promising applications in lighting and display fields. However, the ubiquitous thermal-induced fluorescence quenching in perovskite emitters lacks systematic research, and methods to suppress thermal quenc
