Abstract

Metal halide perovskites have attracted tremendous attention due to their superior photoelectric properties, which led to light-emitting diodes (LEDs) applications. To enhance the poor performance of blue LEDs compared to green and red LEDs, quasi-2-dimensional perovskites, which have the energy funneling effect, were chosen. To maximize the energy funneling effect, it is necessary to rearrange the 2-dimensional phase distribution. The shortened energy transfer pathway can improve radiative recombination. Here, we introduce a variety of metal halide additives for high-performance perovskite LEDs.
