【摘要】 本文报道用晶体场理论对新型稀磁半导体Ｚｎ＿（１－ｘ）Ｃｏ＿ｘＳｅ和Ｚｎ＿（１－ｘ）Ｃｏ＿ｘＳ中Ｃｏ￣（２＋）离子不同能级间的跃迁进行计算的结果。与实验观测结果进行了比较，获得了相应的晶场参量Ｄ＿ｑ，Ｒａｃａｈ静电参量Ｂ，Ｃ和自旋－轨道耦合参数λ。本文对Ｚｎ＿（１－ｘ）Ｃｏ＿ｘＳｅ和Ｚｎ＿（１－ｘ）Ｃｏ＿ｘＳ分别指认了观测到的Ｃｏ￣（２＋）离子能级间的跃迁。对较低能级部分，实验结果与理论计算符合较好。更多还原

【Abstract】 Spectra of the new type diluted magnetic semiconductors Zn_1-xCo_xSe and Zn_1-xCo_xS related to transitions between the different energy level of Co￣（2+） ions for states of d￣7 configuration have been calculated by crystal field theory. The compari-son of calculated and observed spectra of Co￣（2+） ions have been given. Both are in good agreement in the low energy level part. Crystal field D_q,Racah B, C and spin-orbit coupling λ parameters have been obtained and observed spectra of Co￣（2+） in Zn_1-xCo_xSe and Zn_1-xCo_xS have been designeted,respectively.更多还原
