Organic–inorganic hybrid perovskites have drawn considerable attention due to their great potentials in lighting and displaying. Despite great progress being demonstrated in perovskites light-emitting diodes (PeLEDs), the commercialization of PeLEDs was still limited by their low efficiencies and poor device stabilities. Utilizing the metallic nanoparticles was a feasible way to further improve the efficiencies of PeLEDs. Herein, substantially enhanced electroluminescent performance of CH3NH3PbBr3-based PeLEDs were first demonstrated by incorporating plasmonic gold nanoparticles (Au NPs) into the hole injection layer of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS). Compared to the reference device without Au NPs, 109\% enhancement in maximum luminance and 97\% enhancement in maximum EQE were achieved upon 9 vol \% Au NPs doping. Such enhancements can be ascribed to the localized surface plasmon resonance between Au NPs and CH3NH3PbBr3 excitons, as well as the enhanced electrical conductivity of modified PEDOT:PSS. Our studies indicated great potential of Au NPs in developing highly efficient PeLEDs.
