  1. 1. Nanoplasmonic Spectroscopy of Single Nanoparticles Tracking Size and Shape Effects in Pd Hydride Formation

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Svetlana Syrenova; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hole-mask colloidal lithography; enthalpy of formation; palladium nanoparticles and nanocrystals; metal-hydrogen interactions; shrinking-hole colloidal lithography; localized surface plasmon resonance; dark field scattering spectroscopy; single particle spectroscopy; nanoscale effects; plasmonic sensors;

    Abstract : Localized surface plasmon resonance (LSPR) is a phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light that is used for its excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. READ MORE
