ABSTRACT:
This invention relates generally to new luminescent materials. Specifically, this invention relates to the discovery of phosphor materials in the forms of A.sub.2 BX.sub.4, ABX.sub.4-y :M and A.sub.3-z B.sub.5 X.sub.12 :M.sub.z. More specifically, this invention relates to the discovery of phosphor materials having compositions of matter in the forms, Sr.sub.2 CeO.sub.4, (Y.sub.0.82 Al.sub.0.07 La.sub.0.06)VO.sub.4 :Eu.sub.0.05 and (Y.sub.0.5 Gd.sub.0.5).sub.2.97 (Al.sub.0.5 Ga.sub.0.5).sub.5 O.sub.12 :CeO.sub.0.03.
