| Abstract: | The water-soluble Prussian-blue(PB) analogue hexacyanoferrate(HCF) nanoparticles CoHCF has been synthesized by using poly(N-vinyl-2-pyrrolidone) as a protective matrix.Transmission electron microscopy(TEM) images of the synthesized CoHCF shows stable and well cubic dispersed nanoparticles with fairly narrow size distribution.X-ray diffraction(XRD) analysis further identifies a face-centred cubic structure of the nanoparticles.The FTIR spectroscopy are employed to investigate the optical properties of the nanoparticle-PVP composites,showing distinguished optical transitions from conventionally synthesized nanoparticles.The effect of feed ratio of PVP on cobalt ions and the initial pH value on the size are also discussed in the paper. |
