  3. 22. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS

    Författare :Zhaleh Pirzadeh Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localized surface plasmon resonance; interband transition; nanoantenna; nickel nanoplasmonic; coupling;

    Sammanfattning : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). LÄS MER

  4. 23. Resonant Interactions Between Nanoparticle Plasmons and Molecular Excitons

    Författare :Gülis Zengin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface-enhanced absorption; J-aggregates; Localized surface plasmon resonance; strong coupling; Rhodamine 6G; nanoparticles;

    Sammanfattning : Molecular plasmonics involves the study and applications of plasmonic metal nanostructures interacting with molecules. It has been a basis for development of fundamental understandings of light-matter interactions as well as of new technologies, including biological and chemical sensors and plasmon-enhanced spectroscopies.

  5. 24. Nanoplasmonics for Absorption Engineering and Hydrogen Sensing

    Författare :Carl Wadell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium; hydrogen storage; absorption engineering; nanoplasmonic sensing; nanosize effects; plasmon enhanced chemistry; Localized surface plasmon resonance;

    Sammanfattning : When light interacts with metallic nanoparticles smaller than its wavelength it can excite a collective oscillation of the conduction electrons that gives rise to efficient light absorption and scattering. Moreover, locally strongly enhanced electric fields are created around the particles. LÄS MER

  7. 25. Plasmonic Nanostructures for Optical Absorption Engineering and Hydrogen Sensing

    Författare :Carl Wadell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; metal hydride; alloy nanoparticles; palladium; absorption engineering; plasmon enhanced chemistry; nanoplasmonic sensing; nanoparticle size effects; localized surface plasmon resonance; hydrogen sensing;

    Sammanfattning : Nanoplasmonics concerns the interactions between light and metal nanoparticles. In this thesis nanoplasmonics is used in two different ways: i) to control and enhance light absorption, and ii) for optical hydrogen sensing. LÄS MER
