Abstract

The paper is divided to two parts one is a short description of scientific activity of Georges Boulon and my long standing friendship with him, the second part consists of the new findings of increasing fluorescence by surface plasmons studies performed recently in Jerusalem. We describe the synthesis of copper nanoparticles and their incorporation into polyvinylpyrrolidone and into sol-gel matrix co-doped with the fluorescent dye Lumogen F Red 300. The absorption and emission spectra of samples undoped and co-doped with nanoparticles reveal the increase of fluorescence of the dye in presence of copper nanoparticles. The phenomenon arises from scattered light by the nanoparticles.
