Influence of metal nanoparticles on electromagnetic surface waves and laser light scattering
We show that metallic nanoparticles (NP) deposited upon a surface modify its optical properties. Light scattering and its energy level under conditions of surface plasmon resonance are strongly affected by the presence of NP. The results of angle resolved scattering (ARS) measurements of light and scattered light in the configuration of attenuated total reflection by surface plasmon resonance (ATRSPR) are presented. We show that ATRSPR is more sensitive to the presence of NP than ARS.
