Abstract

Abstract The perovskite light‐emitting diode (PeLED) based on lead has the advantages of excellent purity, high efficiency, and good brightness. In order to develop a highly luminescent and deep blue lead halide perovskite light emitting diode, here, a two‐dimensional layered lead perovskite owning the high deep blue photoluminescence quantum yield 80% at 445 nm is reported. In addition, the maximum recording brightness and the peak external quantum efficiency of the PeLED is 1315 cd m−2 and 3.08%, respectively, which outdoes that of previously reported deep blue lead PeLEDs. The half‐life of the device reaches 3.5 h at 5 V. This work clearly shows that the layered lead perovskite will provide a route to fabricate stable and high‐performance deep blue emission PeLEDs.
