摘要：
xMnO center dot (100-x)[As2O3 center dot 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. (C) 2010 Elsevier B.V. All rights reserved.
