A phosphor for color television surface-treated with zinc hydroxide so that zinc hydroxide attaches thereto in an amount below 0.7 part by weight per 100 parts by weight of the phosphor. Phosphor slurries for production of phosphor screens prepared from the phosphor have improved light-exposure sensitivity at the formation of and produced from these slurries phosphor screens showing less color mixing.
