- •
Structural, thermal, and optical features of TeO2 rich glasses were studied.
- •
TeO4, Te3+1, TeO3 units of TeO4; BO3 and BO4 units of B2O3 were identified.
- •
Several glass forming region and thermal stability parameters were evaluated.
- •
All synthesized glasses show high thermal and glass stabilities.
- •
Direct and Indirect optical band gaps were evaluated from absorption spectra.
