Title: Infrared and Raman spectroscopic investigations of xMnO (100-x)[As2O3 TeO2] glass system

Abstract: xMnO·(100−x)[As₂O₃·TeO₂] glass system, with 0≤x≤50 mol %, was prepared and investigated by FT-IR and Raman spectroscopies in order to determine its structure and the changes induced by the increasing of MnO content. The results offered by FT-IR and Raman spectroscopies suggest a structure formed by AsO₃, TeO₄ tbp and TeO₃ tp units. The presence of MnO₂ units was confirmed by FT-IR spectra only for high concentration of MnO.

Key words: As₂O₃·TeO₂ glass matrix; Manganese ions; FT-IR; Raman
