High-Performance Quasi-2D Perovskite Light-Emitting Diodes Via Poly(vinylpyrrolidone) Treatment

High-Performance Quasi-2D Perovskite Light-Emitting Diodes Via Poly(vinylpyrrolidone) Treatment

Abstract In this work, we fabricate poly(vinylpyrrolidone) (PVP)-treated Ruddlesden-Popper two-dimensional (quasi-2D) PPA2(CsPbBr3)2PbBr4 perovskite light-emitting diodes (PeLEDs) and achieved a peak brightness of 10,700 cd m−2 and peak current efficiency of 11.68 cd A−1, threefold and tenfold highe...
