1. Optical properties of silver nanostructures prepared by electron beam lithography
Abstract : In this thesis, electron beam lithography (EBL) has been used to fabricate substrates for studies of nanoparticle optics, in particular for the investigation of noble metal nanoparticles and their tunable optical properties. The strong interaction of metal nanoparticles with light has its origin in the resonant excitation of collective oscillations of conduction electrons, so called localized surface plasmons (LSP).

2. Optical Imaging and Spectroscopy of Metal Nanostructures
Abstract : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. READ MORE

3. Surface Plasmon Photonics: From Optical Properties of Nanoparticles to Single Molecule Surface-enhanced Raman Scattering
Abstract : With the rapid development of nanoscience and nanotechnology, surface plasmon photonics using metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for electronic, optical, and sensor applications. In the nanoscale, the physical and chemical properties of metallic particles, especially their optical properties, strongly depend on size and shape, as well as on surrounding media and structures.

5. Synthesis and Characterization of Some Nanostructured Materials for Visible Light-driven Photo Processes
Abstract : Nanostructured materials for visible light driven photo-processes such as photodegradation of organic pollutants and photoelectrochemical (PEC) water oxidation for hydrogen production are very attractive because of the positive impact on the environment. Metal oxides-based nanostructures are widely used in these photoprocesses due to their unique properties. READ MORE
