Abstract

Chalcogenide glasses As₂_S3 doped with ytterbium were investigated by Raman spectroscopy in order study the structural changes accompanying the incorporation of impurity metal ions in the host glass structure. Doping of A_s2S₃ glasses with small amount of Yb ions, up to 1 % wt., only slightly affect the short-range order structure of the host matrix. For Yb concentration more than 1 % wt. the sharp increase of presence of the additional bands characteristic for the vibrations non-stoichiometric molecular fragments which contain homopolar S-S and As-As bonds was observed. Such changes correlate with data on the thermal properties of such glasses where Tg values were sharply decreased if Yb concentration was more than 1 % wt. No additional bands besides characteristic for As₂S₃ stoichiometric and non-stoichiometric structural units were found. The main observed effect under the introduction of ytterbium into As₂S₃ is the change of relative concentration of the main and non-stoichiometric structural units characteristic for As₂S₃ glasses.
