Abstract
Erbium-doped tellurite glasses (TeO2-ZnO-Na2O3: Er3+ (TZNE)) were elaborated from the melt-quenching method. Various spectroscopic parameters were obtained to evaluate their dependence and the potential of the samples as a laser material in the eye-safe laser wavelength (1.53 μm) as a function of the Er3+ concentration. The dependence of infrared photoluminescence (PL) spectra on doping concentration shows a quenching of the PL intensity for Er3+ concentration above 2 mol%. Such dependence is discussed in terms of interactions between Er3+ ions and OHâ content. FTIR spectra were measured in order to calculate the exact content of OHâ groups in samples. It was found that PL quenching with Er concentration in the tellurite glass is independent of OHâ content. Stimulated cross-section at 1.53 μm was determined and was discussed using the McCumber theory.
