A radiographic intensifying screen is composed of a support and a phosphor layer. The phosphor layer contains a terbium activated gadolinium oxysulfide phosphor. The screen contains a fluorescent dye or pigment which absorbs a portion of luminescence emitted by the oxysulfide phosphor and then emits a light having an emission peak in the wavelength resion of 490 to 600 nm.
