YTTRIUM ALUMINIUM GARNET PHOSPHOR DEPOSITION TECHNIQUE

摘要

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 320C and 780C for about 1 h to 2 h in an oxygen ambient.
