Abstract

Thermal-Lens (TL) for fluorescence quantum efficiency (η) characterizations in a new phosphate glass matrix doped with Nd³⁺ were performed. η studies were accomplish in function of Nd³⁺ concentrations (0.5-3 x 10²⁰ ions/cm³). In addition, fluorescence quenching was studied by measuring the concentration dependence of the fluorescence lifetime. The results obtained by TL and fluorescence lifetime techniques are in good agreement, and corroborate with the theory for an energy transfer process involving a pair of ions, in which the main process occurring is cross-relaxation (CR).
