Long-term ambient air-stable cubic CsPbBr₃ perovskite quantum dots using molecular bromine.

ABSTRACT: We report unprecedented phase stability of cubic CsPbBr₃ quantum dots in ambient air obtained by using Br₂ as halide precursor. Mechanistic investigation reveals the decisive role of temperature-controlled in situ generated, oleylammonium halide species from molecular halogen and amine for the long term stability and emission tunability of CsPbX₃ (X = Br, I) nanocrystals.
