Abstract

produced a standard series of semiconducting tellurite oxide glasses containing vanadium and molybdenum oxides based on ), where X = 10, 15, 20, 25, 30 (mol-%) including quenching method. The influence of MoO3 on the glass transition temperature and photofission energy of this kind was analyzed. The thermal parameters of the used glasses, such as transition temperature (Tg) and thermal stability, were measured using the differential scanning calorimetry (DSC) method. Optical gap energy ( and end () were evaluated as a function of (ZnO) content in the glass. It was found that decreased with the increase of ZnO content, while ZnO content increased. Infrared and Raman spectroscopy, X-ray diffraction and scanning electron microscopy were examined and analyzed as a function of ZnO content in different compositions of such glasses.
