Efficient Visible Quasi-2D Perovskite Light-Emitting Diodes
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.
