FePt nanoparticles (NPs) of 4.5 nm mean diameter were synthesized using iron(III) ethoxide and platinum(II) acetylacetonate as precursors. The reaction proceeded without any reducing agent, providing a facile way of synthesis of FePt NPs. FePt NPs were characterized by transmission electron microscopy (TEM), energy‐dispersive X‐ray fluorescence spectrometry (EDX), and inductively coupled plasma atomic emission spectrometry (ICP‐AES). The average composition of NPs was found to be equiatomic and the composition distribution of each NP was considerably narrow. The spatio‐temporal homogeneity and thermal decomposition mode of iron source are considered to be the reason for the improvement of composition distribution. Phase transfer of FePt NPs from oil phase to water phase was also investigated. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
