晶场J-混合对掺杂Pr^(3+)的几种晶体的能级影响

THE EFFECTS OF CRYSTAL FIELD J-MIXING ON ENERGY LEVELS OF SEVERAL Pr^(3+) DOPED CRYSTALS

通过晶场参量得到三参量(S_k),在此基础上,本文考察了掺杂Pr^(3+)晶体中,由于晶场J-混合作用使得态(aSL)J的重心移动量■((aSL)J)以用态(aSL)J内Stark子能级的第二量σ_E借助■((aSL)J)和σ_E,本文提供了一种选择和评价掺杂Pr^(3+)晶体的晶场理论分析方案的方法.

In terms of crystal field parametrs, three parametrs (S_k) are obtained. On this basis, the shifts ?(αSL)J) in the center of gravitiy of (αSL)J states caused by crystal field J-mixing and second moment σ_E of stark levels in (αSL)J state are examined. By means of ?(αSL)J and σ_E, method for estimating and choosing crystal field analysis scheme of several Pr^(3+) doped crystas is provided.
