Abstract

Infrared spectra and lifetimes of ⁴I_13/2 state of Er³⁺ in tungsten-tellurite glasses doped with different concentrations of Er₂O₃ were measured and studied. Judd-Ofelt analysis on absorption spectra was performed. The lifetime of the ⁴I_13/2 state decreases with the increase of the Er ³⁺ concentration due to energy transfer processes. The energy transfer coefficient of 1.6 × 10^-18 cm³ s ^-1 was obtained. It is observed that the nonradiative relaxation rate of ⁴I_11/2-⁴I_13/2 transition of Er³⁺ in tungsten-tellurite glass is unchanged with the increase of Er³⁺ concentration, and about twice as that in TeO ₂-ZnO-Na₂O glass.
