Title:
PEROVSKITE CRYSTAL, PREPARATION METHOD THEREFOR, AND X-RAY DETECTOR
Document Type and Number:
WIPO Patent Application WO/2022/033501
Kind Code:
A1
Abstract:
A perovskite crystal, a preparation method therefor, and an x-ray detector, the perovskite crystal comprising: a perovskite single crystal and a passivation layer. The passivation layer is a structure formed by combining a surface defect of the perovskite single crystal with A1X1, and the perovskite crystal does not contain A1X1 that has not been combined with the surface defect of the perovskite single crystal. By means of performing passivation modification and processing of the perovskite crystal surface, the ion activating energy of the perovskite crystal is increased, the ion movement phenomenon is improved, and the dark current of an instrument is decreased; an efficent x-ray detector of a perovskite crystal coplanar structure is prepared simultaneously, and possesses high sensitivity and a low detection limit, and achieves careful x-ray imaging and line array imaging.
