| dc.description | The structures of V<sub>2</sub> O<sub>5</sub> -TeO<sub>2</sub> glasses are investigated by means of <sup>125</sup> Te and <sup>51</sup> V static NMR spectroscopies and the local structures around the Te and V atoms are discussed in detail from the respective NMR spectra. The fraction of TeO<sub>3</sub> trigonal pyramids increases and that of TeO<sub>4</sub> trigonal bipyramids decreases with increasing V<sub>2</sub> O<sub>5</sub> content. The structures of V<sub>2</sub> O<sub>5</sub> -TeO<sub>2</sub> glasses are quite different from those of tellurite glasses containing network-modifying oxides. The fraction of VO<sub>4</sub> tetrahedra increases and that of VO<sub>5</sub> trigonal bipyramids decreases with increasing V<sub>2</sub> O<sub>5</sub> content. Both chains consisting of tellurite structural units and those consisting of vanadate structural units contribute to the formation of the glass network in V<sub>2</sub> O<sub>5</sub> -TeO<sub>2</sub> glasses. |
