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