TeO2-BaO-Bi2O3 tellurite optical glasses I.- Glass formation, structural, thermal and optical properties
Original language description
The present study investigates the glass-forming ability (GFA), structural, thermal, and optical properties of the TeO(2)-BaO-Bi(2)O(3) (TeBaBi) glass system, focusing on the mutual substitution trends of its constituent compounds. Prepared glasses were synthesized by the melt-quenching method at 900 degrees C and the GFA was extended by chemical compositions with lower TeO(2) (55-85 mol.%) and higher Bi(2)O(3) (5-15 mol.%) content via optimization of the synthesis process. The introduction of BaO and/or Bi(2)O(3) results in the increase of the glass transition temperature (T(g) approximate to 327-384 degrees C), molar volume (V-g approximate to 28.9-33.1 cm(3)mol(-1)) and optical basicity (OB approximate to 0.97-1.03). Prepared TeBaBi glasses exhibit satisfactory thermal stability and wide spectral region of optical transparency from 0.4-6.5 µm with observed narrowing of optical window with higher TeO2 content. Compositional evolution of T(g) maybe described for the TeBaBi glasses using multilinear regression analysis with high correlation (r >= 0.995) across the whole GFA region. The structure of studied TeBaBi glasses was investigated by Raman scattering and directly compared to the TeO(2)-ZnO-BaO (TZB) glass system prepared and characterized under identical conditions. Structural analysis revealed a similar degree of internal glass structure transformation regardless of whether a divalent zinc cation or trivalent bismuth cation is present.
