Sers-active and recyclable Nb2O5/Au platforms
Original language description
Due to their unique physicochemical properties, metal/metal oxide nanomaterials are gaining increasing attention in the scientific community. One possible and promising application of such materials is their use as recyclable platforms for surface-enhanced Raman scattering (SERS) spectroscopy. Here we explore the possible use of Nb2O5/Au coatings fabricated by magnetron sputtering combined with thermal treatment as SERS-active platforms recyclable by UV-light irradiation. It is shown that the SERS activity of Nb2O5/Au coatings is solely related to the plasmonic character of Au nanostructures that, under optimized conditions allows for the SERS detection of methylene blue down to the concentration of 2 x 10-7 M with a relative standard deviation 15 % in the acquired SERS spectra. Furthermore, it is demonstrated that the Nb2O5/Au coatings may be recycled by UV light. The cleaning efficiency provided by Nb2O5 is exponentially dependent on the UV irradiation time with a characteristic time equal to 1.75 h.
