Abstract
Natural ferrite oxide nanoparticles (NPs) embed with tellurite glasses ((89-x) TeO2-10ZnO-1Er2O3-(x)Fe3O4, (x = 0 – 0.8 mol %)) were prepared by conventional melt quenching method to study the influence of the Fe3O4 NPs concentration on the stuctural properties of the glass. Studies on these glassy materials characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and RAMAN spectroscopic measurements are presented. It is observed that the amorphous nature of the glass is confirmed by x-ray diffraction. The FTIR studies support the formation of Te-O-Fe linkages. The FTIR spectra reveal modification in network structures evidenced from vibrational wave-number shifts of TeO4 and TeO3 structural units. Raman spectroscopy have been manipulated to observe the structural modification of [TeO4] trigonal bipyramidal structural unit.
