Abstract
- Herein, we report a new highly luminescent material, a CsPbBr<subscript>3</subscript>@NH<subscript>4</subscript>Br (CPBr–NB) nanocomposite, formed via an ion-exchange reaction, which can reach up to a few micrometers in size. The CPBr–NB solid-state luminophores with a unique core@shell structure effectively avoid photoluminescence quenching and maintain excellent optical properties of the perovskite nanocrystals. Most importantly, the nanocomposite exhibits excellent water resistance and thermal stability. Such superior optical merits endow them with promising potential in lighting and displays.
