TL;DR: In this paper, the dephasing of particle plasmons was investigated using light-scattering spectroscopy on individual gold nanoparticles, and a drastic reduction of the plasmon de-phasing rate in nanorods as compared to small nanospheres due to a suppression of interband damping was found.

TL;DR: The radiative and nonradiative decay rates of lissamine dye molecules, chemically attached to differently sized gold nanoparticles, are investigated by means of time-resolved fluorescence experiments and theoretical results derived from the Gersten-Nitzan model are compared.

TL;DR: This Review highlights morphology-dependent properties of nonspherical noble metal nanoparticles with a focus on localized surface plasmon resonance and local field enhancement, as well as their applications in various fields including Raman spectroscopy, fluorescence enhancement, analytics and sensing, photothermal therapy, (bio-)diagnostics, and imaging.

TL;DR: The fundamental relationship between radiative lifetime and spectral linewidth of freeexcitons is demonstrated theoretically and experimentally for quasi 2D excitons in GaAs/AlGaAs quantum wells.

TL;DR: In this paper, the authors measured the homogeneous line shape of the surface-plasmon resonance in single gold nanoparticles and observed double-peaked line shapes caused by electromagnetic coupling between close-lying particles.
