| Abstract: | Spectroscopic properties of Ag/Er co-doped soda lime silicate glasses have been studied with the aim of assessing the effective role of silver as a sensitizer for erbium. Changes in spectroscopic properties of Er3+ as a function of silver addition to the base composition have been measured. Transmission electron microscopy (TEM), absorption as well as photoluminescence measurements in the visible and infrared spectral region, particularly 4I13/2 → 4I15/2 transition of the Er3+ ion were performed; excitation wavelengths in the range from 325 to 808 nm were used. Enhancement of the Er3+ luminescence at 1.54 μm was observed when Ag was added. |
