FTIR and Raman studies of Eu3+ ions doped alkali boro tellurite glasses

Abstract

To investigate the structural consequences of Eu3+ ions on alkali boro tellurite glasses, the set of six glass samples of (70-x) B2O3-15TeO2-10Na2O-5PbO-xEu2O3 with x=0, 0.1, 0.2, 0.3, 0.4 and 0.5 mol% glasses were prepared by conventional melt quenching method and X-ray diffraction characterization of the glasses admits the amorphous structure. Also their structural properties were studied by the help of FTIR and Raman spectra. FTIR measurements revealed that the bond structure of the prepared glasses is based on BO3 and BO4 units sitting in different structural groups and also interlinked by TeO3 and TeO4 groups. By Raman spectra, it is clear that the prepared glass samples possessing the boroxol rings and also found that slight variations in glass network of the system is discussed with the variation of Eu3+ ions.To investigate the structural consequences of Eu3+ ions on alkali boro tellurite glasses, the set of six glass samples of (70-x) B2O3-15TeO2-10Na2O-5PbO-xEu2O3 with x=0, 0.1, 0.2, 0.3, 0.4 and 0.5 mol% glasses were prepared by conventional melt quenching method and X-ray diffraction characterization of the glasses admits the amorphous structure.
