The nonoxidizing catalytic noble metal rhodium is introduced for ultraviolet plasmonics.
Planar tripods of 8 nm Rh nanoparticles, synthesized by a modified polyol reduction method,
have a calculated local surface plasmon resonance near 330 nm. By attaching p-

The nonoxidizing catalytic noble metal rhodium is introduced for ultraviolet plasmonics. Planar tripods of 8 nm Rh nanoparticles, synthesized by a modified polyol reduction method, have a calculated local surface plasmon resonance near 330 nm. By attaching p-aminothiophenol, local field-enhanced Raman spectra and accelerated photodamage were observed under near-resonant ultraviolet illumination, while charge transfer simultaneously increased fluorescence for up to 13 min. The combined local field enhancement and charge transfer demonstrate essential steps toward plasmonically enhanced ultraviolet photocatalysis.
