Abstract

Abstract : Efficient quasi‐2D‐structure perovskite light‐emitting diodes (4.90 cd A −1 ) are demonstrated by mixing a 3D‐structured perovskite material (methyl ammonium lead bromide) and a 2D‐structured perovskite material (phenylethyl ammonium lead bromide), which can be ascribed to better film uniformity, enhanced exciton confinement, and reduced trap density.
