Structure of As2S3-Sb2S3 glasses by combined Raman spectroscopy and a thermodynamic modelling approach

Popis výsledku v původním jazyce

The structure of chalcogenide glasses in the pseudo-binary system As2S3-Sb2S3 was investigated by comparing results from the thermodynamic model of Shakhmatkin &amp; Vedishcheva with results obtained by analysis of the Raman spectra of xAs(2)S(3). (100-x)Sb2S3 (x=100; 95; 90; 80; 70; 60; 50; 40 mol%) glasses using the principal component analysis (PCA) method and spectral decomposition using the method of Zakaznova-Herzog &amp; Malfait. The PCA method identified three independent components in the studied spectral series. On the other hand, the thermodynamic modeling identified four components with significant abundance in the studied glasses, i.e. As2S3, Sb2S3, As2S2 and S. Finally, correlation analysis showed that there is a strong linear dependencebetween the concentrations of As2S3, S and As2S2. Using the method of Malfait, partial Raman spectra of (As2S3+As2S2+S), and Sb2S3 were calculated. The experimental spectra were reproduced with excellent accuracy. The obtained results con
