Flat panel X-ray detector

摘要

A flat panel X-ray detector which includes an X-ray-charge conversion film (210, 210a, 210b) converting incident X-rays into electric charges, and a pair of electrodes (212, 503) disposed in contact with both surfaces of the X-ray-charge conversion film The X-ray-charge conversion film (210, 210a, 210b) has a laminate structure including a plurality of metal halide films laminated along direction of c-axis of hexagonal crystal structure and differing in band gap from one another, and halogen atoms contained in the plurality of metal halide films are of the same kind among them. <IMAGE>
