| description | In this paper, the glass systems, TeO<sub>2</sub>–ZnO–BaO (TZB), TeO<sub>2</sub>–ZnO–BaO–Nb<sub>2</sub>O<sub>5</sub> (TZB–Nb) and TeO<sub>2</sub>–ZnO–BaO–MoO<sub>3</sub> (TZB–Mo), were fabricated by the traditional melt-quench protocol for use as mid-infrared (mid-IR) transmitting optical material. The effect of Nb<sub>2</sub>O<sub>5</sub> and MoO<sub>3</sub> on the key glass material properties was studied through various techniques. From the Raman analysis, it was found that the structural modification was clear with the addition of both Nb<sub>2</sub>O<sub>5</sub> and MoO<sub>3</sub> in the TZB system. The transmittance of studied glasses was measured and found that the optical window covered a region from 0.4 to 6 μm. The larger linear refractive index was obtained for the Nb<sub>2</sub>O<sub>5</sub>-doped TZB glass system than that of other studied systems. High glass transition temperature, low thermo-mechanical coefficient and high Knoop hardness were noticed in the Nb<sub>2</sub>O<sub>5</sub>-doped TZB glass system due to the increase in cross-linking density and rigidity in the tellurite network. The results suggest that the Nb<sub>2</sub>O<sub>5</sub>-doped TZB optical glasses could be a promising material for mid-infrared transmitting optics. |
