The nonmonotonic dependences of the extinction and PL spectra in composite samples "monolayer Au -film C60 -film Al" are explained by the excitation of surface plasmon polaritons in Al film by the short-range field of localized surface plasmons in Au nanoparticles and the amplification of the plasmon field as the Au nanoparticle monolayer approaches the Al film. A methodology and a setup with a neodymium laser with a Sagnac resonator is proposed and established for studying the plasmon enhancement of multiphoton absorption of low-energy photons in a semiconductor or semiconductor / metal solar cell.
