<p>A phosphor for use in CRTs comprises YAG particles bound to another and to a substrate by a sulphate compound. The phosphor is prepared by treating YAG particles with sulphuric acid, depositing the treated powder on a non-browning glass, quartz or sapphire substrate, and heating to a temperature between about 320oC and 780oC for about 1 h to 2 h in an oxygen ambient.</p> |
