摘要：

Best of both worlds: Reduction of an organometallic Co precursor on preformed CdSe nanorods yields two distinct semiconducting-magnetic heterostructures (see picture). The selective growth of Co on the tips of CdSe first gives nanosphere-nanorod dimers, which evolve into nanorod-nanorod structures. In the hybrid objects the magnetic properties of Co remain intact, while the luminescence properties of CdSe are affected but not completely quenched. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
