Surface-enhanced Raman scattering in the ultraviolet spectral region: UV-SERS on rhodium and ruthenium electrodes

The first ultraviolet surface-enhanced Raman scattering (UVSERS) spectra of molecules adsorbed onto rough rhodium (Rh) and ruthenium (Ru) metal surfaces are reported. Findings show that UV-SERS, like SERS in the visible, with its unique surface-selectivity has a great potential in UV surface and interfacial science to study a wide variety of adsorbed molecular systems on metal nanoparticles.
