Optical band gap and Raman spectra in AxB(0.2-x)(TeO2)0.8 glasses.

Original language description

Seven different glasses with the molar fraction of TeO2 equal to eighty were prepared from pure oxides. The optical band gap was determined in the region 3.33 - 3.61 eV. The coefficient of the temperature dependence of the optical band gap was found in the region 3.8 x 10-4 - 6.8 x 10-4 eVK-1. From the optical band gap the non-linear refractive index value of the studied glasses was estimated at around 0.85 x 10-11 esu. Reduced Raman scattering spectra indicate structural changes induced, by chemical composition, in TeO2 network due to conversion from TeO4 trigonal bipyramids to TeO3 and TeO3+1 units. A qualitative correlation in TeO4 ? TeO3 and TeO3+1 conversion and the optical band gap was found.
