Optical absorption and structure of impurity Ni${}^{2+}$ center in tungstate-tellurite glass

V. G. Plotnichenko, V. O. Sokolov, G. E. Snopatin +1

Absorption spectra of Ni${}^{2+}$ ions in 22WO${}_3$--78TeO${}_2$ tungstate-tellurite glass were studied and Ni${}^{2+}$ extinction coefficient spectral dependence was derived in the 450 -…
