Method of manufacturing an input screen for an image intensifier |
摘要 |
A method of manufacturing an input screen for an image intensifier which comprises the steps of thermally depositing a phosphor layer of alkaline metal halide on one side of a substrate to provide a phosphor layer formed of columnar crystals extending in a direction substantially perpendicular to the plane of the substrate; treating the surface of the phosphor layer by a liquid material of low boiling point and incapable of dissolving the phosphor, thereby producing cracks extending in a direction substantially perpendicular to the plane of the substrate in said phosphor layer; and forming a photoemissive layer on the surface of the phosphor layer, thereby enabling the phosphor layer to have a high light-guiding property and ensuring the prominent elevation of the resolving power of an image intensifier.
