Abstract
The constitution of glasses in the systems M2O3-TeO2 (M = B and In) was investigated by Raman and infrared spectroscopy. From the relation between the M2O3 content and the intensity ratios of the deconvoluted Raman peaks I(720)/I(665) and I(780)/I(665), it was concluded that In2O3 behaves as a network modifier to yield TeO3-units and that discrete BO3 and BO4 units construct a network of glasses containing boron oxide. A structural model for those glasses was derived which involves three-coordinated oxygen atoms and TeO4 units of an intermediate configuration, O3Teδ+ ...Oδ-.
