本文报道了Eu 3+掺杂的Y2 O3的光致发光强度由于ZnO的加入而得到增强。样品由Y2 O3、Eu 2 O3和ZnO粉末的混合物在1200°C下通过固相反应制备。在Eu 3+的f-f跃迁激发下，掺1mol%ZnO和Y2 O3的样品的光致发光强度比不掺ZnO的样品的光致发光强度提高了约3倍。通过对掺ZnO和不掺ZnO样品的光致发光特性和X射线衍射谱的分析，表明ZnO促进了Eu 3+掺杂到Y2 O3中。
This paper reports an enhancement of the photoluminescence intensity of Eu 3+ -doped Y 2 O 3 caused by the addition of ZnO. Samples were prepared by solid-state reaction of a mixture of Y 2 O 3 , Eu 2 O 3 , and ZnO powders at 1200°C. The photoluminescence intensity of the sample calcined with ZnO of 1 mol % against Y 2 O 3 is about three times higher than that of the ZnO-free sample under the excitations in the f-f transitions of Eu 3+ . It is shown that ZnO promotes the doping of Eu 3+ into Y 2 O 3 , from the analysis of the photoluminescence characteristics and the X-ray diffraction patterns of the samples calcined with or without ZnO.
