Abstract
New x-ray photoconductive compositions are disclosed which are certain composites containing (1) inorganic clusters of VB-VIB semiconductors, VB-VIIB semiconductors, IIB-VIB semiconductos, IIB-VB semiconductors, IIIB-VB semiconductors, IIIB-VIB semiconductors, IB-VIB semiconductors and/or IVB-VIIB semiconductors and (2) polymers which are essentially non-carrier-transporting in the absence of x-rays. Also disclosed is an x-ray radiograpy apparatus which employs an image receptor which is a composite of certain inorganic clusters and polymers. A method is disclosed for enhancing the x-ray absorbing efficiency of a polymer which is essentially non-carrier transporting in the absence of x-rays and the x-ray photoconductivity of said polymer by doping the polymer with an effective amount of clusters having a size within the range of from about 0.001 .mu.m to 10 .mu.m.
