Abstract
This master’s thesis deals with the formation of metal-polymer nanocomposite films and the characterization of their plasmonic properties. In the first part of the study, size-selected Cu nanoparticles (NPs) are deposited on thin films of poly(methyl methacrylate) (PMMA) and polystyrene (PS) utilizing a magnetron sputtering cluster apparatus. Dynamics of the NP embedding as well as effects of annealing on the localized surface plasmon resonance (LSPR) of NPs are studied. Treatment of as-deposited NPs in ozone promoting the formation of a thin oxide shell is found to be a promising way for preserving the LSPR on a long time scale in ambient conditions. In the second part, the cluster beam technique is combined with electron beam lithography to fabricate ordered arrays of Ag NPs. The feasibility of the approach is successfully demonstrated, and initial study of plasmonic properties is carried out.
