Title:
ペロブスカイト系ナノ結晶シンチレータ
Document Type and Number:
Japanese Patent JP7359451
Kind Code:
B2
Abstract:
A nanocrystal scintillator that contains a thin-film layer of perovskite-based quantum dots coated on a substrate layer. The quantum dots each have a formula of CsPbXaY3-a, CH3NH3PbX3, or NH2CH═NH2PbX3, in which each of X and Y, independently, is Cl, Br, or I, and a is 0-3. The substrate layer is an aluminum substrate, a fluoropolymer substrate, a fiber optic plate, a ceramic substrate, or a rubber substrate. Also disclosed are an ionizing radiation detector and an ionizing radiation imaging system containing such a nanocrystal scintillator.
