Abstract
Method of preparing a phosphor suspension by mixing a photosensitive material, a photosensitizer, and a phosphor for the purpose of forming a photosensitive film. The photosensitizer in the suspension is a chromic-acid solution. With such a phosphor suspension, a firmly adhering, uniform and compact phosphor film can be formed on the screen substrate. In addition, the phosphor areas obtained by this method have very sharp boundaries.
