Abstract
Abstract
This paper presents the quasi-two-dimensional (QTD) perovskite (Cs0.9Rb0.1PbBr2.1Cl0.9:PEABr) sky-blue light-emitting diode (LED) was prepared through composition engineering, doping engineering and interface modification engineering by using spin coating, it was succeed fabricated which the PEABr organic cations of large volume were introduced into three-dimensional (2D) perovskite through content proportional control, the solution of potassium bromide (KBr) was doped in the nickel oxide (NiOx) hole injection layer and the interface of the NiOx film and the perovskite film. The optimized luminance and external quantum efficiency (EQE) of the sky-blue LED with Cs0.9Rb0.1PBBr2.1Cl0.9: 80% PEABr were 989 cd/m2 and 0.68%, respectively.
