Raman spectra, structure and thermodynamic model of As2S3 - As2Se3 glasses
Original language description
The structure of chalcogenide glasses of the pseudo-binary system As2S3-As2Se3 was investigated by comparison of the results of the thermodynamic model of Shakhmatkin and Vedishcheva with the results obtained by the analysis of Raman spectra of xAs2S3(1?x)As2Se3 (x=1;0,75;0,5;0,33;0,25 and 0) glasses performed by the PCA (principal component analysis) method and spectral decomposition by the method of Zakaznova-Herzog and Malfait. The PCA method identified three independent components in the studied spectral series. On the other hand, the thermodynamic modelling resulted in four components with significant abundance in the studied glasses, i.e. Se, As2S2, As2S3 a As2Se3. Finally, a correlation analysis showed a strong (correlation coefficient of 0,97)linear dependence between the concentrations of Se and As2S2. Using the method of Malfait, partial Raman spectra of (Se+As2S2), As2S3 and As2Se3 were calculated. The experimental spectra were reproduced with excellent accuracy.
