| Iron oxide nanoparticles of various shapes and sizes have been prepared and studied for possible applications in medicine, and magnetic storage memory. To the best of our knowledge, nanocapsules of iron oxide nanoparticles in the 10-15 nm size domains have not been reported. In this work, we present synthesis of spherical nanocapsules of Fe3O4 for the first time. Mechanism for the formation of these hollow particles is proposed and supported with TEM and powder XRD data. It is shown that choice of the surfactant and temperature of growth solution play a major role in the growth of these magnetic nanoparticles. |
