摘要: A wide range glass system based on the TeO2–WO3–ZnF2 was prepared. number of physical properties, namely, transition temperature, optical energy gap, Urbach energy, basicity, ultrasonic velocity (longitudinal and shear), elastic moduli, Poisson's ratio Debye temperature were investigated by using several techniques such as: differential thermal analysis, dilatometric, UV–NIR–IR spectra pulse-echo. These glasses have a high transmission in visible, near infrared regions, very low OH-vibration absorption bands stability beyond 169 °C. The results indicated that most properties are observed to be dependent ZnF2 content. reported with view drawing fluorotellurite fibres.
