What is Low-frequency Raman spectra and structural correlations in metal oxide glasses about?

Raman and FT-IR studies are reported for the (Ix)TeOz-xMg0 system where 0.05 < x < 0.40. The destruction of the three-dimensional Te04 chain network with increase in MgO concentration is followed by comparing the intensities of the Te03 and TeO, stretching-mode bands in the 700 cm-' spectral region. Examination of the same systems after recrystallization yields spectra in which the basic contour often resembles the band envelope of the initial glasses. The decomposition of the Boson peak and its shoulder leads to the suggestion that the strongest feature in the band mass can always be assigned to the long-range descriptive element but the broad shoulder seems to be related to modes associated with more medium-range external interactions within the polyhedron latticework. 0 1997 Elsevier Science B.V.
