    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticle; hydrogen storage; aluminum; hydrogen sensing; localized surface plasmon resonance; platinum; nanostructure; palladium; nanoparticle plasmon;

    Sammanfattning : The interaction of light with sub-wavelength noble metal nanoparticles and nanostructures has developed into one of the most vibrant themes of nanoscience during the past decade. The optical properties of metal nanoparticles are dominated by so-called nanoparticle plasmons or localized surface plasmon resonances (LSPR). LÄS MER

  4. 13. Optical properties of silver nanostructures prepared by electron beam lithography

    Författare :Linda K Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoelectronics; surface-enhanced Raman spectroscopy; single-electron tunneling; electron-beam lithography; nanofabrication; localized surface plasmon resonance; silver nanoparticles;

    Sammanfattning : 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).

  5. 14. 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

  7. 15. Active magnetoplasmonics for nanoscale distances sensing

    Författare :Irina Zubritskaya; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cobalt; magnetoplasmonics; plasmon ruler; magneto-optical Kerr effect MOKE ; nickel; dimer; localized surface plasmon resonance;

    Sammanfattning : Magnetoplasmonics is an emerging field within nano-photonics that operates with the combination of propagating or localized surface plasmons and magnetism. Active and adaptive magnetoplasmonic components that are capable of controlling light on the nanoscale with external weak magnetic fields are envisioned to push the development of integrated photonic circuits, high-density data storage, or the advanced schemes for bio- and chemo-sensing.
