Abstract

Glasses from xCuO⋅(1-x)[3B2O3⋅0.5PbO⋅0.5Ag2O] (0 ≤ x ≤ 0.1) system were prepared and studied by means of FT-IR absorption and Raman scattering. Both spectroscopic techniques provide information regarding the local structure revealing the presence of borate arrangements such as: di-, tri-, tetra-, penta-, ortho-, meta-, pyro-borate and boroxol rings. It was followed the influence of CuO addition on the short-range order (SRO) of the network in order to obtain information concerning the local structure of copper-doped 3B2O3⋅PbO⋅Ag2O glass matrix. The conversion between the tri-coordinated boron atoms and tetra-coordinated ones was also followed..
