Study of Infrared Absorption Spectroscopy of CdTe:Sm Crystals
CdTe:Sm晶体红外吸收光谱的研究

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.
