Abstract

Structural studies were investigated of glasses in the xGd2O3·(100-x) [0,6TeO2·0,4B2O3] (0≤x ≤30mol%) system. The variations observed in the FTIR spectra were correlated with density measurement. The structural results show that these glasses present characteristic tellurium and boron environments which vary with chemical composition of gadolinium oxide. So that at a small content of gadolinium oxide increase the intensity bands assigned to the [TeO4] and [BO4] units, thus transform the [BO4] units into the [BO3] units and changes progressively the coordination of tellurium from 4 through 3+1 to 3 when the quantity of gadolinium ions increases..
