Abstract
By melt quenching technique, a series of transparent bulk glasses with compositions (75TeO(2)-5Li(2)O-10ZnO-(10-S) Nb2O5-(S) Yb2O3) have been obtained, where S=0.0, 0.5, 1, 1.5, 2, 2.5mol%. For the prepared glass samples, physical properties such as density, molar volume, and oxygen packing density were studied. Spectroscopic parameters such as gain, absorption cross-section, and emission cross-section were measured. Differential scanning calorimetry curves indicated that the prepared glass compositions have a good stability factor. At different wavelengths, Urbach energy, optical band gap, and refractive index were obtained. Effective functional groups were detected by applying Raman and FT-IR spectroscopies. This work showed that the prepared glasses are promising candidates for different optical applications and amplifiers including solid state lasers, sensors, data storage, and optical switches.
