چکیده
|
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.
