Abstract

Epitaxial phosphors of Ce,Tb:YAG containing Lu 3+ and Ga 3+ on YAG (yttrium aluminum garnet) single crystal faceplates have properties which are suitable for projection CRTs. The external efficiency of the single-crystal YAG screen is relatively low. Truncated cone geometry can increase the external efficiency by a factor of 5.2, if such a shape can be formed in the phosphor layer. An anisotropy etching process of YAG has been developed for the fabrication of a YAG luminescent screen with truncated square mesas. A large fraction of the cathodoluminescent can be directed through the untextured front surface of the crystal. An improvement in phosphor efficiency by a factor of 2.3 has been achieved.
