摘要: Multicomposition of Er3+-Yb3+ codoped tellurite oxide, TeO2-ZnO-PbO-TiO2-Na2O glass has been investigated. Detailed spectroscopic study the Judd-Ofelt analysis performed from measured absorption spectrum in order to obtain intensity parameters Ωt (t=2, 4, 6). The calculated values were then utilized determination transition probabilities, radiative lifetimes and branching ratios Er3+ transitions between J(upper)-J(lower) manifolds. Both visible upconversion near-infrared spectra characterized under 980 nm laser diode excitation at room temperature.
