摘要：

Five-fold twinned, starfish-like Rh nanocrystals consisting of five arms (see TEM) have been synthesized in high yields with the use of [{(CF3COO)2Rh}2] as a precursor to completely eliminate oxidative etching from this system. The as-prepared Rh nanocrystals were shown with great performance as a substrate for SERS. (Figure Presented). © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
