My research activity during the Ph. D. period has been focused on the simulation and the experimental characterization of Surface Plasmon Polaritons (SPP). Surface Plasmon Polaritons are evanescent electromagnetic waves that propagate along a metal/dielectric interface. Since their excitation momentum is higher than that of the photons inside the dielectric medium, they cannot be excited just by lighting the interface, but they need some particular coupling configurations. Among all the possible configurations the Kretschmann and the grating are those largely widespread. When the SPP couplin

The search for new methods enabling efficient collection of particulate matter and multifactorial analysis in terms of size distribution, elemental composition, and structural identification represents a key-aspect of current efforts in environmental science. In this thesis a significant part of the effort has been devoted to the problem of collection and concentration of airborne particulate matter on a miniaturised custom chip. For this purpose, I applied original nanofabrication approaches derived from nanotechnology to build a special Si3N4 sieve, capable of trapping the airbor

Abstract:
Plasmonic polymer nanocomposites contain plasmonic nanoparticles that are dispersed within a polymer. The polymer matrix strongly influences the optical properties of plasmonic nanoparticles. It is imperative to understand the interaction between plasmonic nanoparticles and polymers so that one can develop functional devices using nanocomposites. The utilization of plasmonic nanoparticles as fillers has great potential to transform critical nanotechnologies where light management is crucial, such as refractive index based nanosensors, optical coatings, and light actuated devices. Despite the g

Abstract:
This thesis investigated new metal nanoparticle and semiconductor catalyst and photocatalyst systems for achieving fine chemical synthesis from both fossil-fuel sourced reactants and biomass carbohydrate-derived reactants. Photocatalysts for industrially important organic oxidation reactions were developed that efficiently worked with the aid of solar light irradiation, at low temperature and pressure, that avoided the use of hazardous chemicals. The effects on the organic reaction mechanisms of different noble metal nanoparticle and metal oxide nanostructures were explored for these chemical

Abstract:
Abstract Recent advances in materials synthesis resulted in a rediscovery of the low cost copper in its one and two-dimensional forms and project newer applications of this metal in fields not considered before. In this thesis, one-dimensional copper, i.e. nanowires are synthesized by a hydrothermal route and explored for their chemical, electrical, catalytic and plasmonic properties with highlighted advantages, benefited from their size and shape compared to thin film and bulk copper. Characterization of copper nanowires and their native oxides were performed using a number of analytical tech
