[摘要]：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 Er(3+) 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 (4)I(13/2) -> (4)I(15/2) transition of the Er(3+) ion were performed; excitation wavelengths in the range from 325 to 808 nm were used. Enhancement of the Er(3+) luminescence at 1.54 mu m was observed when Ag was added. (C) 2011 Elsevier B.V. All rights reserved.
