ABSTRACT:
A radiation imaging sensor including laminate structure of a phosphorescent layer, a light-transmissive electrode, a photoconductor layer, an insulating layer and an electrode, an applied voltage to the photoconductor layer through the light-transmissive electrode and the electrode is increased sufficiently so that light emitted from the phosphorescent member causes avalanche multiplicaton of the electrons and/or positive holes generated in the photoconductor layer by field sweep inside the photoconductor layer.
