Novel reddish yellow-emitting Ba3(Sc1-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(Sc0.999Ce0.001) 4O9.
