摘要：

(Figure Presented) Length made to order: Controlled reduction of [Pt(acac)2] and decomposition of [Fe(CO)5] in a mixture of oleylamine and octadecene leads to the facile synthesis of FePt nanowires and nanorods with diameters of 2-3 nm (see TEM image). The length of the hanowires/nanorods is tunable from greater than 200 nm down to 20 nm by simply controlling the volume ratio of oleylamine and octadecene. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
