Perovskite quantum dots offer easy synthesis and high performance but suffer from poor heat and moisture stability due to organic components. Here, the authors demonstrate a ligand-engineering strategy to improve the environmental stability of all-inorganic CsPbBr₃ perovskite quantum dots using trioctylphosphine, lead stearate, and chlorobenzene.
