Abstract

Application of DC voltage and moderate temperature induces dissolution of metal nanoparticles in nano-composite materials. In this work spectroscopic ellipsometry is used to monitor changes in multilayered nano-composite coatings as the dissolution process takes place.

Abstract

Metal island films show a characteristic absorption peak related to the surface plasmon resonance of free electrons. This kind of film can be used in absorbing coatings, together with dielectric layers. Such absorbing multilayer coatings, with and without the gradient of the silver mass thickness in metal island films throughout the coating, have been deposited by electron beam evaporation. It is shown experimentally that coatings with a gradient in the mass thickness of silver nanoparticles have higher absorption than equivalent nongradient coatings with the same total mass thickness of silver nanoparticles.

Abstract

We describe the optical properties of gold island films embedded between SiO2and TiO2layers. Plasmonic properties of gold films have been characterized for various combinations of embedded media and used in design of reflectors.
