X-ray radiography using enhanced hybridized colloidal CsPbBr3 nanocrystals (NCs) with 2,5-diphenyloxazole (PPO)

Caption

a, Schematic illustration of the RL of a CsPbA3 NC and a CsPbA3 NC hybridized with PPO. b, The schematic diagram describing the mechanism of hybridized CsPbBr3 NC with PPO. The negatively charged N in the PPO binds to the positively charged Pb sites on the surface of the CsPbBr3 NC and exhibiting the charge transfer under X-ray irradiation. c, X-ray flat panel detector consisting of the hybrid CsPbBr3 NCs+PPO scintillator dispersed in octane and sandwiched by two quartz windows, and schematic of the real-time X-ray imaging system and images of an electric power plug, a biological specimen (crab) containing a piece of metal, and a ballpoint pen containing the same piece of metal on the scintillator panel under X-ray irradiation.
