WebRaman spectroscopic studies showed that the glass network consists of TeO4, TeO3+1, TeO3, WO4 , WO6 and NbO6 units as basic structural units. The ratio of TeO3/TeO4 was determined as a measurement of the non-bridging oxygen / bridging oxygen bonds in the network structure. WebTeO2 glass has been studied by Raman spectroscopy up to the record pressure of 70 GPa. The boson peak frequency ωb exhibits a decrease of the ∂ωb/∂P slope at 5–6 GPa and …
