X-ray-sensitive storage phosphors with the optically stable luminescent centres

NaCl, KCl, KBr and LiF crystals doped by In, Tl, Ni, Pd and Ca were investigated as X-ray-sensitive materials. Influence of the way of doping of an impurity and growing of a crystal on such parameters of a material as: sensitivity to ionising radiation; radiative, optical and thermal stability of the image, obtained after an irradiation is investigated. As a result of the work, media for recording of the X-ray images are developed. These allow to reproduce the images in a mode of a photoluminescence. Spatial resolution and the dynamic range of registration of the developed materials concede to similar parameters of commercial storage luminophores like “Image Plates” based on BaFBr : La. At the same time, as distinct from “Image Plates”, the developed radiophotoluminophores allow a long storage and multiple readout of the information recorded.
