Due to their excellent optical properties, metal halide perovskite quantum dots (QDs) show great potential in light-emitting diodes (LEDs) [1]. However, conventional oleic acid/amine ligands have dynamic instability, significantly affecting surface instability and optical properties [2]. In addition, its insulating properties also limit its application in electroluminescent devices. Here, dual-function ligand DDA-MeS can stabilize chelation on QDs surface and simultaneously passivate surface defects. As a result, the electrical performance of green QDs-LED devices is significantly improved, the external quantum efficiency is increased to 10.18%, the maximum brightness is also increased to 8025 cd/m2, and the turn-on voltage is reduced to 2.5 V. This work also provides a new direction for the realization of high efficiency and high brightness green LED devices with dual-function ligands [3].
