Abstract
An X-ray imagining film that transforms X-ray radiation into visible light by scintillating, includes a substrate and a nanocomposite formed on the substrate. The nanocomposite includes perovskite nanosheets and plural organic chromophores that interact with the perovskite nanosheets through F—Pb bonds. The perovskite nanosheets are selected to absorb the X-ray radiation and emit first light centered on 510 nm, and the plural organic chromophores are selected to absorb second light between 400 and 600 nm, with a peak at 510 nm, and emit the visible light in 500 to 800 nm range.
