title: Near-infrared dispersion and spin-orbit interaction of Co doped (80-x)Sb2O3-20Na2O-xWO3 glasses.
abstract: The present paper discusses the fact that the absorption spectra of doped with 0.1% Co3O4 glasses with the composition (80-x)Sb2O3-20Na2O-xWO3 are measured in the spectral region 1200-1400nm. The optical structure of Co(2+) is analyzed and the energies of the electron transitions in the metal ion are determined. The spin-orbit interaction is thoroughly analyzed. The refractive index n is calculated for the examined sample with x=20mol% WO3.
