Abstract

Ultrathin layers of noble metals obtained by deposition to dielectric substrate during evaporation in high vacuum represent nanostructured matter – noble metal island films (MIFs). Nanoparticles showing interesting optical properties due to the localized surface plasmons (LSP) are formed instead of homogenous layer. Optical properties of noble metal nanoparticles are closely related to their size, shape, distribution and dielectric environment. LSP properties may be tailored by changing deposition parameters (amount of material and substrate temperature) or by changing dielectric environment (dielectric layers below and/or above metal nanoparticles).
