3. 2. Optical Imaging and Spectroscopy of Metal Nanostructures

   Författare :Juris Prikulis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; surface plasmon resonance; surface-enhanced Raman spectroscopy; near-field optical microscopy; optical tweezers;

   Sammanfattning : 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. LÄS MER

4. 3. Near-field scanning optical microscopy and fractal characterization with atomic force microscopy and other methods

   Författare :Anders Mannelquist; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

   Sammanfattning : This thesis is devoted to the development of near-field scanning optical microscopy (NSOM) for aqueous solutions and to fractal characterization of steel surfaces with atomic force microscopy (AFM) and other methods. NSOM combines optical properties from a light microscope and the technique of scanning probe microscopy, SPM (invented in the early 1980’s). LÄS MER
