Long-term ambient air-stable cubic CsPbBr(3) perovskite quantum dots using molecular bromine

We report unprecedented phase stability of cubic CsPbBr(3) quantum dots in ambient air obtained by using Br(2) 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 l...

Descripción
Sumario:We report unprecedented phase stability of cubic CsPbBr(3) quantum dots in ambient air obtained by using Br(2) 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.
