Silver Nanoparticle Effect on Spectral-Kinetic Properties of Thin Nickel Phthalocyanine Films

We have investigated spectral and spectral-kinetic properties of hybrid plasmonic nanocomposites on silver nanoparticle monolayers and thin nickel phthalocyanine films. The spectroscopic results obtained by the femtosecond pump-probe technique demonstrate that a fast optical response in the range of long-wavelength nickel phthalocyanine electronic absorption bands becomes observable and registered when the nickel phthalocyanine thin films contact with silver nanoparticles. This could be assigned to the plasmon-related modification and the enhancement of organic subsistent absorption at steady-state absorption spectra of hybrid nanostructures.
