Abstract

PURPOSE: A phosphor for green luminescence with high brightness and little saturation characteristics suitable for a projection picture tube, which is obtd. by coating a Zn2SiO4:Mn phosphor with a specified phosphor.
CONSTITUTION: After a predetermined amt. of ZnO, SiO2, MnCO3 and a flux such as B2O3 are sufficiently mixed and calcined at about 1,200°C for 3W5hr, the calcined product is sieved to obtain a Zn2SiO4:Mn phosphor. Then 100pts.wt. said phosphor is mixed with a suspension of 1W20pts.wt. at least one phosphor of particle size 0.5W2μ selected from ZnS:Cu, Al; ZnS:Cu, Au, Al; ZnS:Au, Al; (ZnCd)S:Cu, Al and ZnS:Cu, Al and a binder such as water glass in water, and the resulting mixture is dried and sieved to obtain a Zn2SiO4:Mn phosphor coated with a ZnS phosphor.
