The glass matrix was the same for all types of glasses and had a high sodium content in order to allow the fabrication of waveguides using an ion-exchange technique. The absorption spectra of the glasses were measured and the Judd-Ofelt parameters q were obtained from the experimental oscillator strengths of the f &rarr f transitions. Er3+ doped glasses showed a very high quantum efficiency when comparing the calculated radiative decay time with the measured lifetime of the 4I 13/2 metastable level. Ag+ Na+ ion-exchanged planar waveguides were successfully obtained in all types of glasses and characterized by the prism coupling technique. It turned out that the diffusion constant values are very similar for glasses containing different rare-earth ions with the same concentration  while  at least for the Er 3+ doped ones  the diffusion constant changes with the ions concentration. 2004 Elsevier B.V.
