Abstract
PURPOSE: To make the promotion of remarkable improvement in the strength of fluorescent screen, with a luminous flux decline rate maintained as well to about the same degree as a conventional one, by constituting partially the binding component at least with one of alumina sol and silica sol.
CONSTITUTION: For the phosphor solution to be applied to a glass tube wall, is used a material such that, to a solvent with a phosphor like calcium pyrophosphoric acid dispersed, be dispersed a binding agent composed of the material, consisting of at least one of the alumina sol, with the binding component dispersing partially alumina very fine particle into the water, and the silica sol, with a silica very fine particle dispersed into the water, with the remaining part being calcium pyrophosphoric acid, fine powdery alumina, aluminum phosphoric acid, fine powdery silica, etc., though with a less decline of luminous flux, a less superior in the point of binding performance. In this way, strength of the phosphor film can be widely improved.
