Abstract
Glasses of Sb2S3-As2S3 system with nominal composition of As0,4xSb0,4(100-x)S60 (where x= 10, 25, 50, 75 and 100 mol% As2S3) were investigated by different quenching methods and Raman spectroscopy. All studied samples were in the vitreous state. The average coordination number (Z), being equal to 2.4, has indicated that the numbers of neighbors of non-chalcogens (As and Sb) and chalcogens (S and Te) atoms were respectively 3 and 2. These coordination numbers were conditions fulfilled by the atoms to obtain vitreous materials. The vibrations of the SbS3 and AsS3 structural units dominated the Raman spectra of the studied Sb2S3-As2S3 glasses.
期刊介绍：
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
