Modifying quantum dot emission using plasmonic crystal arrays of antennas
Last modified: 2012-01-03
Abstract
We present an experimental study of the modified emission of a layer of quantum dots (QDs), just a few nanometers thick, with plasmonic structures. We show that collective resonances in plasmonic arrays of nanoparticles can lead to a strong modification of the emission due to the modified density of optical states at which the excited QDs can decay and the diffractive coupling of plasmonic resonances into the far-field.
