Abstract:

Magnetic Fe3O4 nanoparticles were synthesized via the coprecipitation of ferrous and ferric ion. The morphology and magnetic properties of the magnetic Fe3O4 nanoparticles were investigated by transmission electron microscopy(TEM) and superconducting quantum interference device. Furthermore, the Fe3O4-porphyrin nanocomposite particles(FeOPNCPs) are prepared with Fe3O4 and porphyrin by sol-gel method. The patterns of FeOPNCPs were also characterized by means of scanning electron microscopy(SEM) and TEM. The optical and magnetic properties of FeOPNCPs were investigated on a UV-Vis spectrophotometer, a fluorescence spectrophotometer and a superconducting quantum interference device. These experimental results show that FeOPNCPs not only possess optical features of porphyrin but also retain the superparamagnetic features of Fe3O4 nanoparticles.
