Fine structure, mechanical characteristics and mid-range order in xZnO–yNa2O–(1-x-y)SiO2 glasses

The differentiation between the behavior of Zn2 + and Na + cations in silicate network is shaded by the lack of characteristic infrared or Raman bands belonging to the modes involving the zinc- or sodium-oxygen bonds. It was shown in this study that the stepwise substitution of Na2O for ZnO in the xZnO–yNa2O–(1-x-y)SiO2 glasses with keeping approximately the same SiO2 content causes the high-frequency shift of the Raman-active boson peak (BP)...
