Homogeneous yellowish and well transparent glasses (Li2O)x(TiO2)x(TeO2)1-2x and
(BaO)x(TiO2)x(TeO2)1-2x , (x = 0.075, 0.1, 0.125) were prepared from corresponding oxides (purity
99+%). For prepared glasses the optical gap values were found in the region 3.2 eV – 3.4 eV and
the temperature (T) coefficient of the optical gap (γ) varies in the narrow region 5.3×10-4 eV/K to
5.9×10-4 eV/K for 300 K < T < 580 K. Estimated values of non-linear refractive index (n2) were
found in the region n2 [m2W-1] = 2.7×10-18 – 3.5×10-18 close to n2 values for similar glasses. Raman
spectra measured indicate that connectivity of (BaO)x(TiO2)x(TeO2)1-2x network is more evolved
than that one for (Li2O)x(TiO2)x(TeO2)1-2x glasses. TiO2 most probably assists to continuous
network formation due to appearance of Te-O-Ti bridges.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
