RADIATION DETECTOR, METHOD FOR MANUFACTURING RADIATION DETECTOR, AND METHOD FOR PRODUCING SUPPORTING SUBSTRATE

摘要

Disclosed is a radiation detector characterized by comprising a scintillator layer formed on one side of a supporting substrate and composed of a phosphor converting radiation into visible light, a plurality of transparent electrodes formed in a matrix on the other side of the supporting substrate, a photoelectric conversion layer formed on the transparent electrodes and containing an organic semiconductor material, and an upper electrode formed on the organic semiconductor layer. This radiation detector is further characterized in that collector elements for focusing visible light emitted from the scintillator layer irradiated with radiation on the organic semiconductor layer are embedded in a matrix in the supporting substrate at positions facing the transparent electrodes.
