摘要：

The compositional dependences of spontaneous emission probabilities of rare-earth ions such as Nd3+ and Er3+ were studied for silicate, phosphate and berate glasses using the Judd-Ofelt theory. The effect of the covalency of the rare-earth ion sites on the emission probabilities was estimated from the variations of the profiles of the absorption spectra in terms of the nephelauxetic effect. The spontaneous emission probabilities which depended on the intensity parameters, Omega(4) and Omega(6), were strongly affected by the ionic packing ratio of the glass host.
