中文摘要：

稀土掺杂荧光粉在固态照明中有良好的应用前景。这里用固相法合成了Y2O3：Eu3＋,Tb3＋荧光粉,粉的相结构用X射线衍射仪进行了表征,发现合成了纯相Y2O3,掺杂的稀土离子未对基质结构产生影响。稀土离子单掺杂的Y2O3荧光粉在各自特征领域表现出良好的发光性质,Y2O3：Tb3＋发射出亮绿光,而Y2O3：Eu3＋发射出亮红光颜色。调控它们的浓度,可以在Y2O3：0.2%Eu3＋,2%Tb3＋处实现白光,详细分析了它们的发光光谱,计算了它们的色坐标,对应的CIE色坐标分别标记在色坐标图中。

英文摘要：

Rare-earth doped phosphors with tunable optical properties have potential applications in solid state lighting, such as display panels and fluorescent lamps. Herein, trivalent Eu3＋, Tb3＋ activated Y2O3 phosphors were synthesized by a solid state process. The phase structure was analyzed by X-ray diffraction. The results show the pure phase of Y2O3 is obtained and RE ions do not exhibit any effect on the structural properties. Single RE ions activated Y2O3 phosphors display their characteristic emission. With Tb3＋ doped in Y2O3, a bright green emission is obtained; when Eu3＋ is introduced into the material Y2O3：Tb3＋, the emission color can be adjusted to white light. The calculated CIE chromaticity coordinates of RE ions activated Y2O3 phosphors confirm the green and white emissions.
