摘要：

The effect of different concentrations of the network modifier Na2O on the position of the Boson peak, observed in the low frequency Raman scattering experiments, is analyzed. Glasses containing 25% Na2O (Na2O . 4SiO(2)) and 33% Na2O (Na2O . 2SiO(2)) are compared with pure SiO2 glass. The observed shift of the Boson peak is interpreted in terms of a change of a correlation length, l, corresponding to some medium range order. This length, l, decreases when the amount of sodium oxide increases. (C) 1999 Elsevier Science B.V. All rights reserved.
