原始语种摘要: Glasses with compositions xTeO2 - (35-x) BaO - 65V2O5 (where x = 5, 10, 15, 20, 25 and 30 mol %) were prepared using a conventional melt quenching method. Densities of the glasses at room temperature were determined with the Archimedes method. The theoretical linear refractive index and optical band gap of the glasses were calculated by the Lorentz-Lorenz equation. The glasses possess high refractive index (2.16 - 2.19) and comparatively narrow band gap (3.9 - 4.1 eV). The third order nonlinear optical susceptibility c(3) was determined by generalized Miller’s rule. It was established that c(3) equal to 0.72 - 0.85x10-12 esu is close to the experimental value of ~10-12 esu measured for pure TeO2 glass and TeO2 containing glasses by other authors using THG method. The refractive index and...
