| 摘 要： | 采用熔融-急冷法制备了系列Ge28Sb6S(66－x)SexSex(x=0,10,20,30摩尔比)硫系玻璃样品.分别测试了样品的密度、折射率、可见-近红外透过光谱、红外透过光谱以及喇曼光谱,并分析了在Ge-Sb-S中引入Se对其物理、光学特性的影响.利用喇曼光谱讨论了玻璃的结构与特性之间的关系.结果表明：随着Se含量的增加,样品的密度和线性折射率都增大,可见和红外截止波长都发生红移,纯硫化物玻璃样品主要由GeS4四面体和SbS3三角锥组成,随着Se逐渐代替S,硫-硒混合样品中逐渐出现了GeS4－xSex结构单元以及链状和环状的Se-Se键. |

| Abstract: | A serial of chalcogenide glasses with the composition of Ge28Sb6S(66－x)Sex(x=0, 10, 20, 30, molar fraction) are prepared by the melt-quenching technique. The densities, refractive indexes, VIS-NIR transmission spectra, IR transmission spectra and Raman spectra of the samples are measured respectively. The impact of the presence of Se on the physical and optical properties of Ge-Sb-S glass system are analyzed. The Raman spectra are used to discuss the relationship between structures and properties. Results show that with increasing Se content, the densities and refractive indexes of the samples increase, and the visible and IR cut-off edges shift towards longer wavelengths. The basic structural units of the pure sulfide glass are GeS4 tetrahedra and SbS3 pyramids. With the substitution of S by Se, the sulfur-selenide-containing samples present GeS4－xSex units and Se-Se homopolar bonds both in rings and in chains. |
