Abstract

The first investigation on the effect of silver co-doping on the photoluminescence (PL) properties of Gd3+ ions in glass is reported. A barium-phosphate matrix is chosen as host, with the glasses being prepared by the melt-quenching technique. The PL spectroscopy assessment performed shows that with the increase in Ag+ concentration, the ultraviolet emission from Gd3+ is progressively enhanced. The data suggests a Ag+→Gd3+ excitation energy transfer occurring under the excitation at 275 nm which is resonant with the 4d10→4d95s1 (1S01D2) and 8S7/26IJ electronic transitions in the silver and gadolinium ions, respectively.
