Abstract
An x-ray electro-photographic recording material is formed of a photo-conductive layer (1) comprised of a selenium-arsenic alloy and positioned on a transparent electrode layer (4), which is positioned on a further layer (3) comprised of an x-ray luminophore and positioned on a reflective surface (2a) of a film carrier layer (2). In usage, with a positive corona charge on the free photo-conductive layer surface (1a) before x-ray exposure, the luminophore-containing layer (3), during x-ray exposure, converts a component (5) of the x-ray radiation (.gamma.) not absorbed by the photo-conductive layer (1) into visible luminescent light (6) which effects an increase of sensitivity in the photo-conductive layer (1). This recording material can be used in x-ray photograph devices.
