Claims
- 1. A method of manufacturing an output phosphor screen for an X-ray image intensifier comprising the steps of:
- dropping a dispersion of infusible spherical silicone resin particles on a water surface to form an aggregate layer of said infusible spherical silicone resin particles on the water surface;
- making said aggregate layer of spherical silicone resin particles adhered on a face plate;
- calcinating said adhered aggregate layer of infusible spherical silicone resin particles in an atmosphere containing oxygen at a temperature of not less than 500.degree. C. t change said aggregate layer of infusible spherical silicone resin particles into a layer of spherical silica particles; and
- forming a phosphor layer on said spherical particle silica layer.
- 2. A method according to claim 1, wherein said particle silica has an average particle size of 0.5 to 3.0 .mu.m.
- 3. A method according to claim 1, wherein said phosphor has a refractive index of more than 1.5.
- 4. A method according to claim 1, wherein said infusible silicone resin is at least one member selected from the group consisting of methylsilicone, ethylsilicone, vinylsilicone, and phenylsilicone.
