Ytterbium doped sodium‐tellurite glasses having composition of (80−x) TeO2−20Na2O‐(x)Yb2O3 (where x = 0.0–2.0 mol%) are prepared by melt quenching technique. The crystallinity of the glass has been examined using X‐ray diffraction technique. All glass are found to be amorphous in nature. Meanwhile the transmission spectroscopy is determine by using Infrared Spectroscopy. It is found that the absorption vibrational spectra occurs at range 3405–3423 cm−1, 1632–1643 cm−1, 1377–1382 cm−1, 721−732 cm−1 and 589–606 cm−1 peaks. The predominant peaks around 700 cm−1 is due to the Te‐O‐Te vibration while peak at 600 cm−1 is due to the vibration of Yb3+ ions. |
