چکیده مقاله:

We report the direct soft chemical synthesis and characterization of a family of face centered cubic (fcc) and partially ordered face centered tetragonal (fct) FePt nanoparticles (NPs) suitable for biomedical applications. Both fcc and partially ordered fct-FePt NPs are synthesized by employing a simple polyol method. By using polyvinyl pyrolidone (PVP) as a stabilizer in various ratios during synthesis, fcc-FePt NPs have been converted into partially ordered fct-FePt NPs at low temperature (300˚C) . The advantages of this process are its simplicity, the short reaction time, easy preparation and dispersibility of the NPs in aqueous media.

Polyol Process Synthesis of Monodispersed FePt Nanoparticles.

Monodispersed FePt nanoparticles are synthesized by reduction of iron(II) acetylacetonate and platinum(II) acetylacetonate with 1,2-hexadecanediol as the reducing reagent in the polyol process. As-prepared FePt nanoparticles are chemically disordered with fcc phase. Transmission electron microscopy (TEM) images show a self-assembled particle array with an average particle size of 3 nm and a sta...
