FT-IR AND RAMAN SPECTROSCOPIC STUDIES OF GADOLINIUM DOPED B_2O_3·TeO_2 GLASS MATRIX

摘要

Glasses from xGd2O3 · (100-x)[B2O3 · TeO2] system with 0 ≤ x ≤ 10 mol% have been prepared and studied by means of FT-IR absorption and Raman scattering. Being complementary spectroscopic techniques, both types of measurements FT-IR and Raman revealed that the network structure of the studied glasses is based on BO3 and BO4 units placed in different structure groups and also TeO4, TeO3 structural units. No absorption characteristic for Gd2O3 was evidenced but some changes in the structure of B2O3 · TeO2 glass matrix are due to its presence.
