Y2O3:xBi3+ (x=0.05-1.0% (mole fraction)) phosphors were synthesized by a solid-phase reaction route. Effect of Bi3+ concentration on the phase composition, microstructure and photoluminescence (PL) performance was investigated. The results show that the lattice parameter and cell volume of Y2O3 host increase with the increase of Bi3+ concentration. In addition, the phosphors are equiaxed grains, and the grain size increases gradually from 250 to 600 nm with the Bi3+ concentration increasing. The emission spectra of Y2O3:Bi3+ phosphors excited by ultraviolet light (λEX=335 nm) are composed of three broadband emission spectra centered at 370 nm, 410 nm and 483 nm. The ultraviolet-emission at 370 nm and blue-light emission at 410 nm appear due to 3Au→1Ag and 3Eu→1Ag electron transitions of S6 sites of Bi3+, respectively. The blue-green emission at 483 nm occurs due to 3B→1A electron transition of C2 sites of Bi3+. The Y2O3:0.25%Bi3+ phosphor shows the optimal PL performance. The concentration quenching occurs when Bi3+ concentration is higher than 0.25% due to the dipole-dipole interaction between Bi3+ ions. The color coordinate of Y2O3:0.25%Bi3+ is (0.159 2, 0.218 1), and the color rendering index Ra is 69.27, indicating that the as-synthesized blue-green phosphors have a broad application prospect in the field of white light-emitting diode.

采用高温固相法合成了Y2O3:xBi3+[x=0.05-1.00%(摩尔分数)]荧光粉,研究了Bi3+掺杂浓度对荧光粉相组成、微观形貌及发光性能的影响。结果表明:Bi3+掺杂量增加会引起Y2O3基质晶格膨胀和晶胞体积增大;荧光粉呈等轴状颗粒形貌,且随着Bi3+掺杂量的增加,粒径逐渐从250 nm增加到600 nm。Y2O3:xBi3+荧光粉在波长为335 nm的紫外光激发下,其发射光谱由370、410和483 nm 3个宽带发射组成。370 nm紫外光发射和410 nm蓝光发射分别是由Bi3+的S6位点的3Au→1Ag和3Eu→1Ag电子跃迁产生,483 nm蓝绿光发射是由C2位点的3B→1A电子跃迁产生。当Bi3+掺杂浓度为0.25%时,荧光粉发光性能最优;掺杂量大于0.25%时,由于Bi3+间的偶极-偶极相互作用,产生浓度猝灭现象。所制备的Y2O3:0.25%Bi3+荧光粉的色坐标为(0.1592、0.2181),显色指数Ra为69.27,表明这种蓝绿色荧光粉在白光LED领域具有良好应用前景。

采用高温固相法合成了Y2O3:xBi3+[x=0.05-1.00%(摩尔分数)]荧光粉,研究了Bi3+掺杂浓度对荧光粉相组成、微观形貌及发光性能的影响。结果表明:Bi3+掺杂量增加会引起Y2O3基质晶格膨胀和晶胞体积增大;荧光粉呈等轴状颗粒形貌,且随着Bi3+掺杂量的增加,粒径逐渐从250 nm增加到600 nm。Y2O3:xBi3+荧光粉在波长为335 nm的紫外光激发下,其发射光谱由370、410和483 nm 3个宽带发射组成。370 nm紫外光发射和410 nm蓝光发射分别是由Bi3+的S6位点的3Au→1Ag和3Eu→1Ag电子跃迁产生,483 nm蓝绿光发射是由C2位点的3B→1A电子跃迁产生。当Bi3+掺杂浓度为0.25%时,荧光粉发光性能最优;掺杂量大于0.25%时,由于Bi3+间的偶极-偶极相互作用,产生浓度猝灭现象。所制备的Y2O3:0.25%Bi3+荧光粉的色坐标为(0.1592、0.2181),显色指数Ra为69.27,表明这种蓝绿色荧光粉在白光LED领域具有良好应用前景。

Y2O3:xBi3+ (x=0.05-1.0% (mole fraction)) phosphors were synthesized by a solid-phase reaction route. Effect of Bi3+ concentration on the phase composition, microstructure and photoluminescence (PL) performance was investigated. The results show that the lattice parameter and cell volume of Y2O3 host increase with the increase of Bi3+ concentration. In addition, the phosphors are equiaxed grains, and the grain size increases gradually from 250 to 600 nm with the Bi3+ concentration increasing. The emission spectra of Y2O3:Bi3+ phosphors excited by ultraviolet light (λEX=335 nm) are composed of three broadband emission spectra centered at 370 nm, 410 nm and 483 nm. The ultraviolet-emission at 370 nm and blue-light emission at 410 nm appear due to 3Au→1Ag and 3Eu→1Ag electron transitions of S6 sites of Bi3+, respectively. The blue-green emission at 483 nm occurs due to 3B→1A electron transition of C2 sites of Bi3+. The Y2O3:0.25%Bi3+ phosphor shows the optimal PL performance. The concentration quenching occurs when Bi3+ concentration is higher than 0.25% due to the dipole-dipole interaction between Bi3+ ions. The color coordinate of Y2O3:0.25%Bi3+ is (0.159 2, 0.218 1), and the color rendering index Ra is 69.27, indicating that the as-synthesized blue-green phosphors have a broad application prospect in the field of white light-emitting diode.
