Effective Medium Description of Plasmonic Couplings in Disordered Polymer and Gold Nanoparticle Composites
Résumé
Disordered gold nanocomposite films were obtained by introducing spherical gold nanoparticles into a polymer matrix. These films were structurally characterized using microscopy techniques, and then analyzed for their effective optical indices using spectroscopic ellipsometry. It is found that even for a low volume fraction of gold nanoparticles ....
