Abstract
A novel CsPbX<sub>3</sub> NCs@BaF<sub>2</sub> scintillation screen is developed for fast and full-color emission under high-energy ray excitation. The light yield of the CsPbBr<sub>3</sub> NCs@BaF<sub>2</sub> can reach up to 6300 photons/MeV and its fast decay time component is about 11 ns.
