Research Abstract

Novel phosphors based on hexagonal type-II rare earth oxycarbonates were synthesized by our original flux method using an eutectic mixture composed of alkaline metal carbonates. Among the oxycarbonate phosphors obtained, a green-emitting terbium-doped gadolinium-yttrium oxycarbonate phosphor showed the highest emission intensity, and the relative emission intensity was 131% of that of a commercial green-emitting lanthanum phosphate phosphor.
