ABSTRACT:
A catholuminescent material consisting essentially of particles of copper-activated zinc sulfide cathodoluminescent phosphor having at least a partial coating of a mixture of a blue pigment of cobalt aluminate and a red pigment of iron oxide wherein the weight ratio of said blue pigment to said red pigment is from about 3.5:1 to about 4.5:1 and the weight percent of said pigments are from about 0.2% to about 2% by weight of catholuminescent phosphor. A process for producing said pigmented phosphor comprises forming the appropriate aqueous slurries by proper pH control and then by the addition of collodial silica, the pigment is coated onto the phosphor particles.
