Description
  • Li2O-TiO2-TeO2 a BaO-TiO2-TeO2 skla byla připravena a zkoumány jejich vlastnosti. (cs)
  • 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 5.3x10-4 eV/K to 5.9x10-4 eV/K for 300 K < T < 580 K. Estimated values of non-linear refractive index (n2) were found in the region n2 [m2W-1] = 2.7x10-18 ? 3.5x10-18 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.
