Abstract
In this study the Raman spectroscopy is employed to investigate the structural properties of Ge-As-S chalcogenide glasses. Obtained Raman data show that studied chalcogenides are nanostructurized materials. Raman spectra of Ge-As-S samples showed that the backbones of the studied samples consist of AsS3/2 pyramidal units, edge- and corner-shared Ge(S1/2)4 tetrahedral units. Compositional changes in studied glasses result in the evolution of the observed Raman bands. Such dependences of characteristic constituent Raman bands' intensities showed that Ge-As-S samples contain different nanophases whose concentration is changing along chosen compositional cross-section.
本文采用拉曼光谱研究了锗砷硫系玻璃的结构特性。得到的拉曼数据表明，所研究的硫族化合物是纳米结构材料。Ge- as -s样品的拉曼光谱表明，研究样品的骨架由AsS3/2锥体单元和边角共享的Ge(S1/2)4四面体单元组成。所研究的玻璃的成分变化导致了所观察到的拉曼带的演变。特征组分拉曼谱带强度的依赖性表明，Ge-As-S样品中含有不同的纳米相，其浓度沿所选择的组分截面变化。
