ABSTRACT:
Small particle lanthanum, thulium phosphate phosphors are produced by thermal decomposition of gels or solutions or powders including lanthanum, thulium, lithium and alkaline earth salts and an organic precursor such as trimethyl phosphate and boric acid at a temperature well below the normal temperature of solid state reaction. The phosphor of the present invention has the empirical formula:
