Long-term ambient air-stable cubic CsPbBr$_3$ perovskite quantum dots using molecular bromine
Résumé
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 CsPbX$_3$ (X = Br, I) nanocrystals.
