摘要
(Graph Presented) Multipodal Rh nanocrystals (see HRTEM image of a tripod) prepared through a polyol synthesis display surface plasmon resonance bands in the visible region. Surface-enhanced Raman scattering from 4-mercaptopyridine adsorbed on Rh multipods is 19-times stronger than that from Rh nanocubes. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
