采用传统的固相反应法在1400° C下合成了BaLu1.94Al4SiO12:0.06Ce3+(BLASO:0.06Ce3+)绿色荧光粉。BLASO:0.06Ce3+具有石榴石结构,空间群为Ia 3 π d,晶格常数a= 11.9222(0)π. BLASO的发射峰:0.0 6 Ce 3+位于5 13 nm处,在2 5 ° C下,当激发波长为4 5 0 nm时,其光致发光量子产率为92.4%。Blaso:0.06Ce3+具有优异的热性能,在200° C下的光致发光强度仅降低到室温值的91.5%。采用BLASO:0.0 6 Ce 3+作为绿色荧光粉制备的荧光粉转换白色LED器件具有良好的光学性能,其Ra= 88.5,CCT= 35 6 2 K,CIE 1931色坐标为(x= 0.40 41,y= 0.395 1)。结果表明,BLASO:0.06Ce3+荧光粉在开发高显色性、热稳定性、暖白光LED方面具有很好的应用前景。
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.
