Abstract

Abstract : Melt quenching technique was used to prepare (30-x)Li2 O–xNa2 O–40B2 O3 –30GeO2 glasses (x = 0, 5, 10, 20 & 30 mol %). The room temperature infrared spectra of the powdered glass samples were recorded in the range of 400–2000cm −1 . Raman measurements were performed in the range of 200–2000cm −1 at room temperature. Raman and Infrared spectroscopy was utilized for structural study of this glass system. Specific modes of vibration and peak position were identified from de-convolution of infrared and Raman spectra using Gaussian fitting. Ge–O–Ge bonds' symmetrical stretching vibrations related to 3 members GeO4 rings were allotted to the IR band of 483 cm −1 . The strongest Raman band was allotted to symmetrical stretching vibrations of Ge–O in GeO4 having one non-bridging oxygen with 3 bridging oxygens at 797 cm −1 . The observed Raman and IR spectra of various specimens are utilized here to explain the structural characteristics of current glass.
