UV-SERS monitoring of plasmonic photodegradation of biomolecules on aluminum platforms decorated with rhodium nanoparticles.

ABSTRACT: In the search for novel nanostructured materials for UV plasmonics, only a limited number of choices are available. Materials such as aluminum, rhodium, and gallium can be used. One of the most interesting applications of UV plasmonics is surface-enhanced Raman spectroscopy. It can be extended to this spectral range to explore the spectral properties of biomolecules that have only a small cross-section in the visible spectral range. We have recently reported on a functional substrate based on nanoporous aluminum decorated with rhodium nanoparticles. This system exhibited an interesting behavior with UV excitation at 266 nm and an unexpected decrease in Raman intensity with an increase in rhodium nanoparticle concentration. We proposed that this effect can be due to the difficult access of
