    <description descriptionType="Abstract">X-ray diffraction, infrared (IR), Raman spectroscopy and scanning electron microscope techniques have been used to investigate the microstructural properties of the glass materials. In this work, a new type of tellurite based optical glasses with TeO2/Nb2O5/TiO2 for different xNb(2)O(5) (x = 5, 10, 15, and 20 mol.%) glass compositions at constant 5 mol.% TiO2 ratio were prepared. The effect of Nb2O5 contents on the structural unit of (95 - x)TeO2-(x)Nb2O5-5TiO(2) glass network, and the intensity ratios of the Raman peaks were investigated. The results indicate that for different Nb2O5 content 5 to 20 mol.% in the glass system, three vibrational peaks around 650, 800, and 920 cm(-1) which correspond to the structural bonding of the glass were observed in the range of 500-2000 cm(-1) for the IR spectra. Furthermore, from the Raman results a structural evolution was determined with the number of structural units such as [NbO6](7-), TeO3+1 (polyhedra), TeO4 (trigonal bipyramids), TeO3 (trigonal pyramids) or TeO3+1 (polyhedra), and [NbO4](3-) for this ternary glass system.</description>
