We demonstrate a facile, low-cost and room-temperature method of anion exchange in cesium lead bromide nanocrystals (CsPbBr<sub>3</sub> NCs), embedded into a polymer matrix. The anion exchange occurs upon exposure of the solid CsPbBr<sub>3</sub> NCs/PDMS nanocomposite to a controlled anion precursor gas atmosphere. The rate and extent of the anion exchange reaction can be controlled <i>via</i> the variation of either the exposure time or the relative concentration of the anion precursor gas. Pos ...[more]
