Abstract

PEROVSKITE-BASED NANOCRYSTAL SCINTILLATORS A nanocrystal scintillator that contains a thin-film layer of perovskite-based quantum dots, each having a formula of CsPbXaY3-a, CH3NH3PbX3, or NH2CH=NH2PbX3; the nanocrystal scintillator capable of generating X-ray-excited emissions. Also disclosed are an X- ray detector and an X-ray imaging system, each containing such a nanocrystal scintillator. Further disclosed is a method for fabricating an X-ray imaging system. (Figure 1)
