It is possible to obtain a cathode ray ray with increased performance and high screen brightness. In particular, when an alkaline earth metal sulfide phosphor is used as the sulfur-containing phosphor (A), mixing the additive (B) increases the stability of the water glass aqueous solution and prolongs gelation. The precipitation and application of the phosphor composition can be carried out continuously in large quantities.
