At the metallic surfaces, light with frequencies below the frequency of the surface plasmons is re?
uences the optical properties of metallic nanostructures, as these are controlled by the interaction of light with surface plasmons.
Usually, the oscillation frequency of the surface plasmons is in the visible region.
In the case of resonance with incoming photons, one observes strong surface plasmon resonance absorption peaks; this is an entirely different mechanism of absorption as compared to semiconducting particles, where quantum con?
The frequency of surface plasmon resonance absorp- tion changes only slightly with particle size; therefore, the optical properties of metallic nanoparticles are, within a relatively broad range of particle sizes, almost unin?
