Title: Towards improved precision in the quantification of surface-enhanced Raman scattering (SERS) enhancement factors: a renewed approach
Abstract: This paper demonstrates a renewed procedure for the quantification of Raman scattering (SERS) enhancement factors with precision. The principle of this method relies on deducting the Raman scattering (RRS) contribution from surface-enhanced Raman scattering (SERRS) to end up with the surface (SERS) effect alone. We employed (4 alpha-Co(II)TAPc), a Raman-and electrochemically redoxactive chromophore, as a molecule for RRS and SERRS experiments. The number of 4 molecules contributing to RRS and SERRS phenomena on inactive glassy carbon (GC) and plasmon active GC/Au surfaces, has been precisely estimated by cyclic voltammetry Furthermore, the SERS substrate enhancement factor (SSEF) by our approach is compared with the traditionally employed We also demonstrate that the present approach of SSEF can be applied for any kind of different SERS substrates by choosing an appropriate laser line and probe molecule.
