Abstract
The efficiency of (ZnCd)S, (ZnCd)Se and Zn(SeTe) solid solutions, dope d with copper and chlorine, as X-ray downconverting phosphors for phot odetectors is investigated. It is found, that the phosphors based on t he solid solutions of the group II-VI wide-bandgap compounds and prepa red in oxygen-free medium, can increase the photodetectors sensitivity to X-ray radiation more than one order of magnitude and enhance the d etectors photocurrent versus radiant flux characteristics linearity.
