This paper describes the fabrication of plasmonic focusing, free-standing rod-sheath hetero-nanostructures based on electrochemical templated synthesis and selective chemical etching. These hetero-nanostructures take advantage of plasmon interference together with field enhancements due to sharp junction structures to function as stand-alone SERS substrates containing Raman hot spots at the interface of the rod and sheath segments. This result is investigated with empirical and theoretical (disc ...[more]
