Abstract

Glasses of Sb₂S₃-As₂S₃ system with nominal composition of As_0,4xSb_0,4(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.
