摘要：

Since infrared spectroscopy and density are advantageous tools for the investigations of glasses, we have used them to obtain information concerning the local structure of xGd(2)O(3)center dot(100-x)[4Bi(2)O(3)center dot GeO2] glass system, with 0 <= x <= 30 mol%. Gd2O3 play the network modifier role in the studied glasses and determines, by progressive addition, the increase of structural volume difference between the hypothetical crystalline compounds and the quenched samples. FTIR spectroscopy data show that the glass structure consists on the BiO6. GeO4 and GeO6 structural units, and the conversion among these units mainly depends on the Gd2O3 content.
