While perovskite quantum dots (PeQDs) have attracted attention due to their excellent optical properties, their performance can be further improved by optimizing their ligands. In this study, we report a more than twofold enhancement in the external quantum efficiency (EQE) of PeQDs-based light-emitting diodes (LEDs) through designing unique ligands for LEDs applications.
