Abstract
An X-ray phosphor composition consisting essentially of a material having the formula EQU (Y.sub.1.sub.-x In.sub.x PO.sub.4) wherein X has a value of from about 0.005 to about 0.2, emits in the area of the spectrum of from about 300 to about 460 nanometers when excited by X-rays. A method of preparing the phosphor composition and an X-ray intensifying screen containing the same are described.
