Quantification of the chemical enhancement contribution to surface enhanced Raman scattering (SERS) — •Bonito Thielert1,2, Bo Liu1,2, Rainer Stosch3, and Peter Lemmens1,2 — 1IPKM, TU-BS, Braunschweig, Germany — 2LENA, TU-BS, Braunschweig, Germany — 3Abt. 3.1, PTB, Braunschweig, Germany
In our aim to quantify chemical enhancement (CM) in SERS we study light-matter interactions of molecules on dedicated Au nanorod arrays. The latter are based on AAO substrates and allow tunable geometries and interaction parameters of the plasmonic array. Using Rhodamine 6G and Malachite Green we analyze the effect of light-induced degradation and mobility on the SERS intensity. Work supported by DFG-RTG 1952/2 "NanoMet" and Braunschweig-IGSM.
