Abstract
Nanoscale structures made from coinage metals such as gold or silver possess localized surface plasmon-polariton (LSP) excitations when the material interacts with light of the correct frequency and polarization. LSPs generated from freestanding 2D nanorod arrays have been applied to enable surface-enhanced Raman scattering (SERS) and surface enhanced fluorescence (SEF) spectra from Rhodamine 6G molecules adsorbed on the surface of the arrays. We study the conditions that optimize SERS and SEF from self-standing Au nanorod arrays by studying the effect of changing the surrounding environment using Al2O3 as a dielectric spacer layer.
