Abstract BaLu 1.94 Al 4 SiO 12: 0.06 Ce 3+(BLASO: 0.06 Ce 3+) green-emitting phosphor could be easily obtained by a conventional solid-state reaction method at 1400° C. BLASO: 0.06 Ce 3+ possesses the garnet structure (Ia 3 ̅ d space group) with the lattice parameter a= 11.9222 (0) Å. The emission peak of BLASO: 0.06 Ce 3+ is located at 513 nm and its photoluminescent quantum yield is determined to be 92.4% at 25° C when excited at 450 nm. BLASO: 0.06 Ce 3+ presents excellent thermal properties, with the photoluminescence intensity at 200° C only decreased to 91.5% of its room temperature value. A phosphor-converted white LED device fabricated by using BLASO: 0.06 Ce 3+ as the green phosphor exhibits good optical performance with Ra= 88.5, CCT= 3562 K and CIE1931 chromaticity coordinates as (x= 0.4041, y= 0.3951). The results indicate that BLASO: 0.06 Ce 3+ phosphor has strong potential applications in developing high color rendering, thermally stable, warm-white LEDs.
