Abstract: Abstract Realizing high electroluminescence dissymmetric factor and high external quantum efficiency at the same time is challenging in light-emitting diodes with direct circularly polarized emission. Here, we show that high electroluminescence dissymmetric factor and high external quantum efficiency can be simultaneously achieved in light-emitting diodes based on chiral perovskite quantum dots. Specifically, chiral perovskite quantum dots with chiral-induced spin selectivity can concurrently serve as localized radiative recombination centers of spin-polarized carriers for circularly polarized emission, thereby suppressing the relaxation of spins, Meanwhile, improving the chiral ligand exchange efficiency is found to synergistically promote their spin selectivity and optoelectronic properties so that chiroptoelectronic performance of resulting devices can be facilitated. Our device simultaneously exhibits high electroluminescence dissymmetric factor (R: 0.285 and S: 0.251) and high external quantum efficiency (R: 16.8% and S: 16%), demonstrating their potential in constructing high-performance chiral light sources.
