Plasmonic Enhancement by a Continuous Gold Underlayer: Application to SERS Sensing

Abstract : In this paper, we report on an improved enhancement of the surface-enhanced Raman scattering (SERS) effect. Such improvement is obtained by using a continuous gold film (underlayer), which is added below an array of gold nanostructures. Two types of nanostructures were studied to validate our results: regular disk arrays with two diameters (110 and 210 nm) and lines with a width of 110 nm, all on a gold film of 30 nm thick. A supplementary gain of one order of magnitude on the SERS enhancement factor (EF) was experimentally demonstrated for several excitation wavelengths: 633, 660, and 785 nm. With such SERS substrates, EFs of 10 7 are observed for thiophenol detection. This opens the way towards routine and reliable detection of molecules at low concentration.
