| dc.description.abstract | Highly monodisperse water soluble cobalt ferrite (CoFe2O4) and manganese ferrite (MnFe2O4) nanoparticles were synthesised by the hot injection thermolysis of pivalate clusters as single source precursors. The precursors [Fe2CoO(O2CtBu) 6(HO2CtBu)3] (1) and [Fe2MnO(O2CtBu)6 (HO2CtBu)3] (2) were decomposed in a mixture of polyvinyl pyrrolidone (PVP) (capping agent)and triethyleneglycol (TREG) (solvent) at 285 1C to produce cobalt ferrite and manganese ferrite nanoparticles, respectively. The effect of the PVP on the size and morphology of the nanoparticles synthesised was investigated. Smaller sized nanoparticles of cobalt and manganese ferrite nanoparticles were obtained at higher PVP concentration and larger nanoparticles were produced at lower PVP concentrations. The ferrite nanoparticles produced are monodisperse, directly dispersible in water without any further sizes election/post synthesis procedure.The nanoparticles were characterised by powder X-ray diffraction (p-XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), energy dispersive spectroscopy (EDS) and selected area electron diffraction (SAED). | en_US |
