Brillouin and low-frequency Raman studies of TeO2–BaO–TiO2 glasses Original Research Article

The dynamic behavior of the ternary TeO2–BaO–TiO2 glasses were investigated by Brillouin and low-frequency Raman spectroscopies. The evolution of both the elastic constant, C11, and the Boson peak maximum position, ωmax, are sensitive to a structural modification with the composition and to the type of cation (Ti4+, Ba2+).
