IR study of Pb-Sr titanate borosilicate glasses
Source abstract
Abstract
The infrared spectra (IR) of various glass compositions in the glass system, [(PbxSr1−x)O·TiO2]-[2SiO2·B2O3]-[BaO·K2O]-[La2O3], were recorded over a continuous spectral range (400–4000 cm−1) to study their structure systematically. IR spectrum of each glass composition shows a number of absorption bands. These bands are strongly influenced by the increasing substitution of SrO for PbO. Various bands shift with composition. Absorption peaks occur due to the vibrational mode of the borate network in these glasses. The vibrational modes of the borate network are seen to be mainly due to the asymmetric stretching relaxation of the B-O bond of trigonal BO3 units. More splitting is observed in strontium-rich composition.
