CoFeAu nanoparticles were successfully synthesized by polyol process with the use of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) as the sur-factant ,C14 H29CH(OH)CH2OH as the reducing agent ,cobalt acetylacetonate ,iron acetylacet-onate and gold acetate as precursors .The FT-IR study confirmed the PEO-PPO-PEO molecules on the surface of the CoFeAu nanoparticles .The X-ray diffraction identified the crystallograph-ic parameter 0 .406 nm of the face-centered cubic structure and showed the nanoparticles have good crystallinity .Whereas a UV-Vis near IR spectrophotometer and a vibrating sample mag-netometer were respectively applied to prove the good optical and magnetic properties of the CoFeAu nanoparticles .Such multi-functional CoFeAu nanoparticles show promising applica-tions in the catalytic ,magnetic ,photoelectric and biomedical fields .
