We show here how luminescence of fluorescent dyes and lanthanide complexes in sol–gel matrix can be intensified as a result of interaction of the species with silver nanoparticles. Preparation of silver nanoparticles in sol–gel composite precursor is outlined and their structural characterization are presented. Zirconia-glymo and Glymo-polyurethane-silica were used as host matrices for silver nanoparticles and the fluorescence species. The intensification of fluorescence was demonstrated by steady state spectroscopy.
