Edition: Celebrating the 60th Anniversary of Professor David Avnir


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.

We are greatly thankful to Prof. J. Lakowicz for providing his resent review and to Prof. Oscar Malta for helpful discussion clarifying very important points.
