| 摘 要： | 实验测定了YAlO3:Nd3+的子能级R1,R2的热移位值。研究了单声子项中积分主值的行为,并计入光频支项对子能级热移位的贡献。用包含Raman项、单声子顶、光频支项的公式拟合计算子能级R1,R2的热移位,拟合计算值与实验值符合得很好。

| Abstract: | Thermal shifts of sub-levels R1 and R2 in YA1O3:Nd3+ has been measured. The behavious of the principal value of the integral in the single-phonon term have been investigated and the contribution of optical frequency branch to thermal shifts of sub-levels has been considered.By using the formulas involving Raman term, single-phonon term and term of optical frequency branch, thermal shifts of sub-levels R1 and R2 are calculated. Satisfactory agreement between the results of the theory and experimental values is obtained. |
