Abstract
In the paper we are investigating the interactions between the europium ions and the silver nanoparticles embedded in an antimony-germanate-silicate glass. Modification of Sb 2 O 3 - GeO 2 - SiO 2 - Al 2 O 3 - Na2O glass system by AgNO3 (up to 0.4 mol.%) allows us to obtain a visible effect of thermo-chemical reduction of Ag+ ions and characteristic absorption band localized at the wavelength of 450 nm. The effect of Ag concentration on structural and luminescent properties of fabricated glasses doped with 0.2 mol. % Eu 2 O 3 have been investigated. According to the luminescence analysis, in glass samples with Ag excited at 405 nm, the enhancement of 5D 0 → 7F 2 transition (616 nm) in Eu3+ ions has been observed just after the melting process. Based on these results, an effective embedding way of Ag particles in RE - doped optical fibers has been discussed.
