Abstract

The main spectroscopic parameters (intensity parameters, radiative life times, branching ratios, quantum efficiency and emission cross-section of the ⁴F_3/2→⁴I_9/2 transition) of the 38PbO-62SiO₂ glass doped with Nd³⁺ are evaluated using the standard Judd-Ofelt theory. Remarkably low values of the intensity parameters Ω_2,4,6 are explained by structural modifications of the Nd ³⁺ surroundings caused by presence of the Pb ions.
