The photoluminescence from the fullerene C60 thin films on array of the gold nanoparticles was studied at various energies of exciting laser photons. An enhancement of the photoluminescence of C60 film on array of Au nanoparticles was observed. The observed enhancement is due to strong local field of surface plasmon excited in the gold nanoparticles. Tuning of the exciting photon energy allowed to control the quantum yield of C60 film photoluminescence. When the exciting photon energy is close to the surface plasmon resonance, the quantum yield reaches its maximum. This fact confirms the resonant character of the surface plasmon enhancement of the studied photoluminescence of C60 film.
