    摘要： In an intensifying screen composed of a support, a fluorescent layer disposed on the support and a protective layer disposed on the fluorescent layer, the fluorescent layer is composed of one or more phosphors selected from the group consisting of a terbium activated rare earth oxysulfide phosphor, a divalent europium activated alkali earth metal fluorohalide phosphor and a silver activated sulfide phosphor, and the protective layer is a light absorption layer which absorbs a part of light emitted by the fluorescent layer.

    摘要： A radiographic intensifying screen having high radiographic image quality is composed of a support and a fluorescent layer formed on the support. The fluorescent layer contains a pigment coated phosphor in which pigment particles adhere to the surface of the phosphor and partly absorb the light emitted by the phosphor.
