AbstractEfficient inorganic perovskite light-emitting diodes (PeLEDs) with an ultrathin perovskite emission layer (similar to 30 nm) were realized by doping Lewis base polyethylene glycol (PEG) into CsPbBr3 films. PEG in the perovskite films not only physically fills the crystal boundaries but also interacts with the perovskite crystals to passivate the crystal grains, reduce nonradiative recombination, and ensure efficient luminance and high efficiency. As a result, promoted brightness, current efficiency (CE), and external quantum efficiency (EQE) were achieved. The nonradiative decay rate of the PEG:CsPbBr3 composite film is 1 order of magnitude less than that of the neat CsPbBr3 film. After further optimization of the molar ratio between CsBr and PbBr2, a peak CE of 19 cd/A, a maximum EQE of 5.34%, and a maximum brightness of 36600 cd/m(2) were achieved, demonstrating the interaction between PEG and the precursors. The results are expected to offer some helpful implications in optimizing the polymer-assisted PeLEDs with ultrathin emission layers, which might have potential application in see-through displays.
