给出了Yb 3+掺杂的Y2 O3、Lu 2 O3和Gd 2 O3在室温下的吸收和发射光谱。Y_2O_3和Lu_2O_3为紧密的立方结构,表现出与Gd_2O_3单斜结构中Yb ~(3+)不同的Yb ~(3+)相似光谱。在这里,我们使用一种新的方法来研究和优化的主要光谱特性,只有一个浓度梯度样品。最后对Y_2O_3、Lu_2O_3和Gd_2O_3单晶中Yb ~(3+)的Stark能级和拉曼振动进行了归属。
Absorption and emission spectra are given for Yb3+-doped Y2O3, Lu2O3and Gd2O3at room temperature. Y2O3and Lu2O3as close cubic matrices, show Yb3+similar spectra different of Yb3+in Gd2O3monoclinic structure. Here, we use a new method to study and optimize the main spectroscopic properties with only one concentration gradient sample. Finally, assignments of Yb3+Stark levels and Raman vibrations in Y2O3, Lu2O3and Gd2O3single crystal are given.
