Paper Abstract

In this paper we probe the surface enhanced fluorescence (SEF) and Raman scattering (SERS) from arrays of selfstanding Au nanorod arrays embedded within a porous alumina template (AAO). By controlling the thickness of the AAO matrix both SEF and SERS are observed exhibiting an inverse relationship. SERS and SEF show a nonlinear response to the removal of AAO matrix due to an inhomogeneous plasmon activity across the nanorod. Optimization of the level of alumina matrix thickness optimizes conditions for obtaining either maximized SERS, SEF or for simultaneously observing both SERS and SEF together.
