Abstract

PURPOSE:To prevent the scattering of light in the direction parallel to the surface of fluorescent layer while to improve such performance as the contrast, resolution, etc. by providing recesses in the surface of a substrate through the irradiation of laser beam while providing cracks corresponding to said recesses. CONSTITUTION:The laser beam is irradiated onto the surface of a substrate 1 made of a thin plate such as Al, ceramic, etc. having plain surface to produce many recesses 11. When depositing the fluorescent material such as CaI on the surface of said substrate 1, cracks 21 corresponding to said recesses are provided in the fluorescent layer 2 grown longitudinally in pillar shape. The pattern of said crack 21 is quite the same as that of said recesses 11. Then a passivation film 31 of such as SiO2 is formed as the input face, and a photoelectric layer 3 of bi-alkali or multialkali is formed. Consequently the contrast is considerably improved while simultaneously the resolution is improved.
