| 摘要: 利用溶剂热法合成了2种四元硫化物Rb2CdSbS3（SH）（1）和Rb2HgSb4S8（2）。单晶X射线衍射分析表明，化合物1为一维链状结构，由[CdSbS3（SH）]2-阴离子和Rb+阳离子组成。化合物2为二维层状结构，由[HgSb4S8]2-阴离子和Rb+阳离子组成。固体紫外可见漫反射光谱分析结果表明，化合物1和2的带隙分别为2.06和2.15 eV。荧光分析结果表明化合物1和2均具有黄光发射特性。 |

| Abstract: Two quaternary chalcogenides Rb2CdSbS3(SH) (1) and Rb2HgSb4S8 (2) were synthesized by solvothermal method. Single crystal X-ray diffraction analysis shows that compound 1 is 1D chain structure and composed of[CdSbS3(SH)]2- anion and Rb+ cation. Compound 2 is a 2D layered structure and composed of[HgSb4S8]2- anion and Rb+ cation. Solid-state UV-Vis diffuse reflectance spectra showed that the band gaps of compounds 1 and 2 were 2.06 and 2.15 eV, respectively. Fluorescence analysis showed that compounds 1 and 2 had yellow emission characteristics. |
