单斜RbInS_2、CsInS_2的红外光谱及拉曼光谱

Infrared Spectra and Raman Spectra of Monoclinic RblnS_2 and CsInS_2

我们采用传统的助熔剂合成方法制备单斜RbInS2 、CsInS2 晶体并对它们的红外光谱和拉曼光谱进行研究。与RbInS2 相比 ,CsInS2 的红外吸收峰和拉曼吸收峰向长波方向移动。红外光谱和拉曼光谱均表明单斜RbInS2 、CsInS2 具有很好的红外透过性能。

Monoclinic RbInS 2 and CsInS 2 were prepared b y the traditional flux method and their IR and Raman spectra were studied.The IR and Raman absorption bands of CsInS 2 shift to lower frequency compared with R bInS 2.IR and Raman spectra show that monoclinic RbInS 2 and CsInS 2 exhibit good infrared transmission.
