Paper Abstract

By electron-beam lithography (EBL) 1D and 2D arrangements of metal nanoparticles can be fabricated with high control of particle shape, particle orientation and arrangement pattern. As the plasmon resonances in metal nanoparticles are primarily determined by the particle shape, their optical properties can be controlled within a wide range by design of the particle geometry parameters. Additionally, the control of local field effects, due to electrodynamic particle interaction, is possible by tailoring the interparticle distances and the specific arrangement pattern. Such EBL-produced metal nanoparticle thin films can be optimised for several optical properties, e.g. for defined dichroic behaviour. In particular our metal nanoparticle films can be used very efficiently in the field of surface enhanced optical effects. By plasmon resonance control defined energetic interactions between fluorophors and the metal nanoparticle can be obtained, leading to a control of balance between radiating and non-radiating deexcitation pathways. Thus, the fluorophor-particle interaction modifies the fluorophor's absorption properties, its fluorescence intensities, fluorescence lifetime and photobleaching rates.
