Surface defect mitigation via alkyl-ligand-controlled purification for stable and high-luminescence perovskite quantum dots

Tae Yong Im,

Jin Young Kim,

Woongsik Jang

et al.

Abstract: We investigated the interaction of methyl acetate with amine ligands of different alkyl-chain lengths. As a result, it was confirmed that PQDs using hexylamine (C6) had the best luminescence (QY: 79.2%) and stability due to the enhanced MeOAc effect.
