Abstract：

Metal　halide　perovskite　quantum　dots　(QDs)　have　significant　potential　for　application　in　light-emitting　diodes　(LED)　owing　to　their　superior　optical　properties.　However,　the　dynamic　instability　of　traditional　oleic　acid/amine　ligands　has　a　considerable　impact　on　the　optical　and　chemical　properties　of　the　surface.　Additionally,　one　of　its　insulating　qualities　restricts　the　practical　application　of　electroluminescent　devices.　In　this　case,　the　dual-function　ligand　DDA-MeS　can　passivate　surface　defects　while　also　stabilizing　chelation　on　QDs　surface.　As　a　result,　the　electrical　performance　of　green　QDs-LED　devices　is　greatly　enhanced,　the　external　quantum　efficiency　is　raised　to　10.18%,　the　maximum　brightness　is　also　boosted　to　8025　cd/m2,　and　the　turn-on　voltage　is　decreased　to　2.5　V.　This　work　also　provides　a　novel　strategy　for　the　development　of　green　LED　devices　with　dual-function　ligands　that　can　be　highly　effective　and　bright.　©　2023　Elsevier　Ltd
