Abstract
An intensifying screen for producing a latent image in a silver halide radiographic element upon exposure to an image pattern of X-radiation is disclosed. The intensifying screen contains a fluorescent layer containing a phosphor capable of absorbing X-radiation and emitting longer wavelength electromagnetic radiation comprised of monoclinic crystals of a titanium activated zirconium hafnium oxide phosphor host. The phosphor contains in an amount sufficient to enhance emission of the longer wavelength electromagnetic radiation at least one alkali metal in combination with at least one Group 14 dopant chosen from Periods 3, 4 and 5.
