Absorption sp ectrum analysis and crystal-field calculation of Nd3+ dop ed in GdTaO4 crystal

  • 摘要: 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)σ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。
    Abstract: 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.
