Abstract

Fourier transform infrared (FT-IR) spectra and Fourier transform Raman (FT-Raman) spectra of the xTb4O7(1-x)[3Bi2O3·PbO] glass system with 0.01≤x≤0.12 were recorded and analyzed with the aim of determining some of its structural characteristics. The FT-IR spectra of the samples were recorded for the 400-1300 cm−1 range using an Equinox 55 Bruker spectrometer. The FT-Raman spectra were recorded for the 70-1000 cm−1 region using the same equipment. The observed IR and Raman features were assigned to various vibration modes of the studied vitreous network..
