ABSTRACT:
A phosphor for use in CRTs comprises (Y.sub.3-p-m-n R.sub.p Pr.sub.m Tb.sub.n)(Al.sub.5-q Z.sub.q)O.sub.12, where R is a lanthanide element and Z is a Group III element. One embodiment described is a single crystal of (Y.sub.3-m-n Pr.sub.m Tb.sub.n)Al.sub.5 O.sub.12 in which the trivalent Pr and Tb activators exhibit co-emission and the phosphor emits white light.
