Abstract

Novel reddish yellow-emitting Ba₃(Sc_1-xCe _x)₄O₉ (0 ≤ x ≤ 0.01) phosphors were synthesized in a single-phase form by a conventional solid-state reaction method. These phosphors exhibited excellent optical absorption in the blue-light region and showed reddish yellow emission with a peak at 583nm due to the 5d → 4f transition of Ce³⁺ under excitation at 437 nm. By optimizing the Ce³⁺ concentration, the maximum emission intensity was obtained for Ba₃(Sc_0.999Ce_0.001) ₄O₉.
