Abstract

Abstract : High‐performance, multicolor perovskite light‐emitting diodes are fabricated in a two‐step solution process by Liang‐Sheng Liao, Wei Lei, Qiaoliang Bao, and co‐workers in article number1606874 . A specially designed n ‐type semiconductor consisting of Ca‐doped ZnO nanoparticles is used as the electron transport layer (ETL). Combining a tunable ETL with a solution process pushes perovskite‐based materials a step closer to practical application in multicolor light‐emitting devices.
