论文：Effect of Eu,Tb codoping on the luminescent properties of Y2O3 nanorods
a b s t r a c t
Red-emitting Y2O3:Eu3 +and green-emitting Y2O3:Tb3+and Y2O3:Eu3 +, Tb3 +nanorods were synthesizedby hydrothermal method. Their structure and micromorphology have been analyzed by X-ray powderdiffraction (XRD) and transmission electron microscopy (TEM). The photoluminescence (PL) property ofY2O3:Eu3 +,Tb3 +phosphor was investigated. In the same host (Y2O3), upon excitation with ultraviolet(UV) irradiation, it is shown that there are strong emissions at around 610 and 545 nm corresponding tothe forced electric dipole5D0–7F2transition of Eu3 +and5D4–7F5transition of Tb3 +, respectively.Different qualities of Eu3 +and Tb3 +ions are induced into the Y2O3lattice. From the excitation spectrum,we speculate that there exists energy transfer from Tb3 +to Eu3 +ions .The emission color of powdersreveals regular change in the separation of light emission. These powders can meet with the request ofoptical display material for different colors or can be potentially used as labels for biological molecules.
Y2O3共掺杂Eu3+和Tb3+的纳米晶体的发光性能
摘要
本文采用水热合成法制备纳米结构的红色荧光粉Y2O3：Eu3+、绿色荧光粉Y2O3：Tb3+和荧光粉Y2O3：Eu3+，Tb3+。并通过XED和TEM对样品的结构和微观形态进行了分析，对荧光粉Y2O3：Eu3+，Tb3+的发光性质进行了分析。研究发现，在相同的基质Y2O3中和紫外光激发下，有两个强烈的发射峰（610 nm，545 nm），分别是由Eu–O的电荷迁移5D0—7F2和Tb3+的5D4—7F5跃迁吸收形成的。不同质量的Eu3+和Tb3+共掺杂Y2O3，从激发光谱中我们推测，存在Tb3+向Eu3+的能量传递过程。发射峰的颜色揭示了光发射的分离规律。因此，这种荧光粉能够满足不同颜色的光学显示材料，并且可能作为生物分子的标签。
