Abstract
An X-ray intensifying screen made from a mixture of yttrium tantalate and lanthanum oxyhalide phosphors is described. This screen, when used to expose a silver halide element, e.g., conventional grain or tabular grain element, will produce superior image resolution compared to similar screens made using single phosphors alone.
