    Abstract : 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). READ MORE

  5. 3. Nanoplasmonics for Absorption Engineering and Hydrogen Sensing

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

    Abstract : 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. READ MORE

  6. 4. Charge Separation on Localized Surface Plasmon and Hot Carrier Transfer to Semiconductors

    Author : Yocefu Hattori; Jacinto Sá; Stephan Link; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonics; hot carrier; metal nanoparticles; semiconductors; ultrafast transient absorption spectroscopy; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The relatively recent discovery that plasmonic nanoparticles generate energetic electron-hole pairs known as hot carriers has been the source of interest from many scientific groups. The capability to extract these short-lived hot carriers from metal nanoparticles (NPs) might potentially lead to applications in solar cells, photodetection, and photocatalysis. READ MORE

  7. 5. Probing nanoscale phenomena with nanoplasmonic sensors
