摘要
采用固相法以Li2SO4作助熔剂制备了Yb3+:Y3NbO7多晶,通过X射线粉末衍射用Rietveld全谱拟合确定了其结构,研究了它的吸收和光致发光。Yb3+:Y3NbO7的光致发光峰位于973,1040和1083 nm;吸收谱峰位于863,975和1040 nm。Yb3+:Y3NbO7表现出强的晶场能级分裂,基态晶场分裂约为1022 cm-1。Yb3+:Y3NbO7具有比Yb3+YAG更宽吸收光谱和发射谱,有利于实现超短脉冲和可调谐激光输出,有望成为新型Yb激光材料。
Abstract
The Yb3+:Y3NbO7 polycrystalline powder is fabricated by the solid-phase method using Li2SO4 as flux. The structure of Yb3+:Y3NbO7 is determined by Retvield fitting to X-ray powder diffraction. The photoluminescence spectra of the Yb3+:Y3NbO7 power show three peaks at 975, 1040 and 1083 nm. The absorption spectra has the peaks at 863, 913, 975 and 1040 nm. The Yb3+:Y3NbO7 has relatively strong crystal field with the group 2F7/2 state splitting value 1022 cm-1. Compared with Yb3+YAG, Yb3+:Y3NbO7 with the large absorption and emission spectra bands is advantageous for tunable and ultrafast pulse laser output and will become a new promising Yb laser material.
