Nanoscale spectroscopy with optical antennas

Author affiliations


Optical antennas made of gold nanoparticles are used to enhance the spectroscopic response of single molecules. With a scannable optical half-wave antenna in the form of a gold nanorod we achieve a spatial resolution of 20nm in fluorescence imaging. We explore simultaneous fluorescence and Raman enhancement of dye molecules in the junction of two gold nanoparticles and find similar enhancements as a function of interparticle distance for both fluorescence and Raman scattering. We compare our results with theoretical predictions and provide possible explanations.
