Determination of the Surface Plasmon Polariton Extraction Efficiency from a Self-Assembled Plasmonic Crystal

Abstract : We experimentally measure and analytically describe the fluorescence enhancement obtained by depositing CdSe/CdS nanocrystals onto a gold plasmonic crystal, a two-dimensional grating of macroscopic size obtained by gold deposition on a self-assembled opal. We show evidences of nanocrystals near-field coupling to the gold surface plasmon polaritons (SPP) followed by grating-induced SPP reemission to far-field. We develop a theoretical framework and an original method in order to evaluate, from photoluminescence experiments, the SPP extraction efficiency of a grating.
