采用提拉法生长出了钕掺杂钽酸钆重闪烁单斜激光晶体(Nd3+:GdTaO4). 分别测试了该晶体a向、b向和c向的吸收光谱(波段为260-2000 nm), 对其中Nd3+ 的实验能级进行了分析指认. 确定了Nd3+:GdTaO4的102个实验Stark能级, 拟合了其自由离子参数和晶体场参数, 均方根误差(拟合精度) 为12.66 cm-1. 并将拟合得到的Nd3+:GdTaO4实验结果与文献中已报道的Nd3+:GdxLu1-xTaO4 (x=0.85)的自由离子参数和晶体场参数进行了比较. 结果表明, 参数化Stark能级的拟合结果与实验光谱符合得较好.

In this paper, Nd3+-doped GdTaO4 laser crystal for scintillator with high density is successfully grown by the Czochralski method, and the absorption spectra are measured along the a, b and c directions in a wide wavelength range of 260-2000 nm. The experimental energy levels for Nd3+ are analyzed and identified. The free-ions and crystal-field parameters are fitted by the experimental energy levels with the root mean square deviation of 12.66 cm-1, and 102 Stark energy levels for Nd3+ in GdTaO4 host crystal are assigned. The fitting results of free-ions and crystal-field parameters are compared with those already reported for Nd3+:GdxLu1-xTaO4 (x=0.85) crystal. It indicates that the fitting results of Stark energy levels agree well with the experimental spectra.-
