| 摘 要： | 在室温下测量了掺钕钨酸钾钆(Nd3 ∶KGW)晶体三个晶轴方向的吸收光谱,其吸收谱带强度明显显示各向异性。将Judd-O felt(J-O)理论进行修正,使其扩展应用于处理各晶轴方向的吸收光谱,计算出三个晶轴方向的各光谱带吸收系数、电偶极跃迁振子强度,其结果说明了Nd3 :KGW吸收光谱存在着各向异性。同时还研究了该材料在812nm激发下的上转换荧光特性,观察到较强的蓝色荧光。

| Abstract: | Absorption spectra of Nd~(3 ):KGW crystal for the three crystallographic axes were investigated at room temperature.The absorption band intensities distinctly revealed the anisotropy of Nd~(3 ):KGW.The Judd-Ofelt theory was modified and applied to the treatment of the anisotropic absorption spectra.The absorption coefficients and the electric dipole oscillator strengths of various bands were calculated for three crystallographic axes of Nd~(3 ):KGW crystals.The results indicate the anisotropy of the optical absorption of Nd~(3 ):KGW. The validity of the modified Judd-Ofelt approach is discussed in detail.Moreover,we report the up-conversion luminescence of Nd~(3 ):KGW crystal pumped with 812nm wavelength.The analysis reveals that Nd~(3 ):KGW crystal has potential use in blue emitting up-conversion materials. |
