Abstract

The incorporation of phenylethylammonium bromide (PEABr) into a fully inorganic CsPbBr₃ perovskite framework led to the formation of mixed-dimensional perovskites, which enhanced the photoluminescence due to efficient energy funnelling and morphological improvements. With a PEABr:CsPbBr₃ ratio of 0.8:1, PeLEDs with a current efficiency of 6.16 cd A^-1 and an EQE value of 1.97% have been achieved.
