Abstract

The samples from the xCuO·(1-x)[2GeO2·PbO·0.2Ag2O] glass system (0 ≤ x ≤ 0.05) were prepared and studied by means of FTIR absorption and Raman scattering. Both techniques revealed that germanium is disposed in the samples structure as GeO4 tetrahedral units. Moreover, from the Raman data has also detected the presence of the GeO6 octahedra units in the glasses structure. With the CuO addition in the samples take place a change in the germanium atom coordination from four-fold to six-fold. The short range order of the network was found to be affected by the copper ions additions..
