Abstract

Pigment-adhered fluorescent screen for colour TV CRT'S is produced by forming colloidal precipitation of metallic hydroxide on the surface of the fluorescent. Thus, the mixture of Eu activated Y oxysulphide(Y2O2S: Eu) 100 wt.%, Fe2O3 2 wt.%, 2% Zn salt soln 1 wt.% and deionized water 300 wt.% is mixed and added with NH3 to adjust pH7. The product is washed with 300 wt. % deionized water and dryed at 110 deg. C.
