Abstract
It is shown with IR spectral investigations that the short range order of certain tellurite glasses, obtained from monomineral crystalline phases, is similar to that of the crystals. They may contain the following polyhedra: TeO4-trigonal bipyramids (C2v symmetry), deformed TeO4 groups, TeO3 trigonal pyramids (C3v point symmetry), or combinations of these polyhedra. The introduction of V2O5 and MoO3 in the binary glasses leads to a TeO4 → TeO3 transition. MoO3 delays the decay of TeO4 groups in a wider concentration range.
