We have investigated spectral and spectral-kinetic properties of hybrid (organic semiconductor-plasmonic metal) nanocomposites on the base of silver nanoparticle monolayers and thin nickel phthalocyanine (NiPc) films. The spectroscopic results obtained by the femtosecond pump-probe technique demonstrate an enhancement of the fast optical response in the range of long-wavelength NiPc electronic absorption bands when the NiPc thin films contact with silver nanoparticles. This could be assigned to the plasmon-related modification and the enhancement of hybrid structures absorption at its steady-state absorption spectra.
