【摘要】 在12K和300K下测量了半磁半导体Zn_0.095Co_0.05S和Zn_0.97Ni_0.03S的吸收光谱,分别发现3个新的吸收峰。根据晶体场理论和群论分析结果,它们分别对应于Co²⁺的⁴A₂（F）→²T₁（H）、⁴A₂（F）→²T₁（G）和⁴A₂（F）→²T₂（P）的跃迁吸收及Ni²⁺的³T₁（F）→¹A₁（G）,³T₁（F）→¹T₁（G）和³T₁（F）→¹E（G）的跃迁吸收,并用晶体场理论分析了跃迁的选择定则和跃迁的相对强度。更多还原

【Abstract】 The absorption spectra of Zn_0.95Co_0.05S and Zn_0.97Ni_0.03S have been measured at 300K and 12K. Three absorption peaks have been observed in Zn_0.05Co_0.05S and Zn_0.97 Ni_0.03S, respectively, which are attributed to the transitions of ⁴A₂（F）→²T₁ （H）, ⁴A₂（F）→²T₁（G） and ⁴A₂（F）→²T₂ （P） of Co²⁺ and the transitions of ³T₁（F）→¹A₁（G）, ³T₁（F）→¹T₁（G） and ³T₁（F）→¹E₁（G） of Ni²⁺, respectively, in the light of crystal field theory and group theory. In addition, the selection rule of transition and the transition intensity have been discussed by the crystal field theory.更多还原
