| 摘 要： | 通过对Ｔｉ：Ａｌ２Ｏ３晶体的不同取向的电子顺磁共振（ＥＰＲ）研究，认为在９３Ｋ温度下观测到的ｇ＝２．００的强烈各向异性的共振线是来自于Ｔｉ：Ａｌ２Ｏ３晶体中的Ｔｉ３＋离子２Ｔ２ｇ能态的中间能级１Ｅ１／２的顺磁共振吸收。而室温下观察到的ｇ≈２．００的吸收线是由Ｔｉ３＋离子２Ｔ２ｇ能态上能级２Ａ１的共振吸收产生的。由晶体场理论进行的计算与上述结果基本符合。

| Abstract: | EPR studies on Ti:Al2O3 crystal with different orientations of the optical axis of c with respect to the septic magnetic field were performed at 93 K and room temperature. A strongly anisotropic resonant line at 93 K with g=2. 00, and lines with g = 2. 00 at room temperature were attributed respectively to the electronic spin transtions of the first and upper excitation energy level 1E1/2 and 2A1 of the ground state of Ti3+ ions in Ti:Al2O3 crystal. The assignments were in agreement with both the far infrared spectral measurements and g factor calculations using crystal field theory. |
