Abstract
The glasses within composition 65TeO(2)-9Nb(2)O(5)-5Li(2)O-15LiCI-5PbO-1.0La(2)O(3) in mol% doped with x(Er2O3), where x= 0, 20000, 25000 and 30000 ppm were prepared by melt-quenching technique. The thermal and optical properties of these glasses were estimated using differential scanning calorimetric (DSC), and ultraviolet/visible/near-infrared (UV/Vis/NIR) spectroscopy, respectively. The results of the thermal analysis indicate that Er3+ ions modified prepared host glass has high thermal stability and anti-crystallization process. The density, oxygen packing density, molar volumes, oxygen molar volume, molar refraction, metallization criterion, molar polarizability, linear refractive index n, third-order non-linear susceptibility and two-photon absorption coefficient were calculated. It was found that, the linear refractive index increases otherwise decrease in the optical energy gap with an increase of Era(3+) ions. The structure of the glasses through Raman spectroscopy from 200 to 1200 nm was scanned.
