摘要：

Several modified silicate glass samples activated with erbium ions at two different doping rates, namely 0.2 and 0.5 mol%, exhibit at room temperature a fine-structured emission band around 1.5 mu m. The decay of luminescence from the Er(3+)4I(13/2) metastable level is found to evolve according to a single-exponential law and a lifetime as long as 14.2 ms is measured from the glass with the lower erbium concentration. An estimation of the corresponding radiative lifetime, tau(rad), is achieved on the basis of various theoretical models. Internal gain curves resulting from absorption and stimulated emission cross sections are also shown. A 75% quantum efficiency is deduced for the less Er3+ concentrated glass, which is nearly the highest one obtained from silica based doped-glasses.
