摘要
本文报道了CdTe: Sm晶体红外吸收光谱的研究结果.根据立方晶体场理论和Sm离子4f能级间的跃迁特性,分析确定了 CdTe:Sm晶体中 Sm^(2+)、Sm^(3+)离子在晶格中的位置类型及其晶体场特性,用点电荷模型计算了不同位置的Sm^(3+)周围的晶体场参数.
The investigation results of infrared absorption spectroscopy of CdTe:Sm crystals arereported. According to the theory of cubic crystal-field and the characteristic transitions be-tween 4f level of Sm ions, the type of site of Sm^(2+) and Sm^(3+) are analyzed. The parametersof crystal-field surrounding Sm^(3+) with different site type are calculated by using the pointcharge model.
