Er-doped sodium-niobium phosphate glasses have been produced by the melting technique. Their optical properties have been fully characterized and show a broad fluorescence band around 1.5 micrometers . The fluorescence lifetime of the 4I13/2 metastable state is long enough to make these glasses suitable to be used in optical ampl9ification devices. Waveguides have been produced by diluted Ag+/Na+ ion exchange and their properties are described here.
