XRD and IR studies of Yb(3+) doped tellurite glass
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...

| Summary: | 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. |
