  1. 21. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing

    Författare :Christoph Langhammer; Chalmers University of Technology; []
    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

    Författare :Irina Zubritskaya; Chalmers University of Technology; []
    Nyckelord :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.
