Local structure of glasses in the As2S3Sb2S3 system

The local structure of glasses of composition As2(1 - x)Sb2xS3 with x = 0−0.8 is studied by different techniques: 121Sb Mössbauer spectroscopy, infrared and optical absorption experiments. The results are consistent with a model of the glasses formed by a random distribution of AsS3 and SbS3 trigona...

Description
Summary:The local structure of glasses of composition As2(1 - x)Sb2xS3 with x = 0−0.8 is studied by different techniques: 121Sb Mössbauer spectroscopy, infrared and optical absorption experiments. The results are consistent with a model of the glasses formed by a random distribution of AsS3 and SbS3 trigonal pyramidal units connected by sulphur atoms. The variations in the experimental data with Sb2S3 concentration can be correlated with the substitution of Sb atoms for As atoms.
