The　fluorescence　spectra　of　fullerene　were　first　observed　to　change　greatly　in　the　system　of　C-60/C-70-pyridine-gold　hydrosol,　due　to　the　adsorption　of　the　fullerene　molecules　on　the　gold　nanoparticles.　The　energy　transfers　between　C-60　molecules　and　gold　nanoparticles,　leading　to　the　quenching　and　enhancement　of　fluorescence　bands　centered　at　450　and　700　nm,　respectively.　The　fluorescence　bands　in　the　range　from　550　to　800　nm　of　C-70　are　enhanced,　arising　from　the　increased　local　field　intensity　through　the　excitation　of　surface　plasmon　resonance　of　gold　nanoparticles,　(c)　2005　Elsevier　B.V.　All　rights　reserved.
