All-inorganic perovskite nanocrystal materials: new generation of scintillators for high quality X-ray imaging

Scintillating materials, which can convert high energy X-ray radiation into visible luminescence [1], are crucial parts of Xray imaging technology. Since the discovery of X-ray in 1895,scintillating materials have witnessed wild applications in various fields, including security inspection, space exploration, nondestructive detection, and medical diagnostics [2,3].Conventional scintillators are generally large inorganic crystals and can only be grown at high temperature, which significantly increases the manufacturing difficulty and cost. The lumines-
