Abstract
An aqueous route for the synthesis of bifunctional iron oxide hybrid core shell using CdS as the shell materials has been described. The as-grown particles have been characterised using X-ray diffraction, high resolution transmission electron microscopy (HRTEM), superconducting quantum interference device, optical absorbance and photoluminescence spectroscopy. HRTEM images demonstrated successful formation of the core–shell structure. The as-grown core shell structures have been shown to be strongly photoluminescent while retaining the room temperature superparamagnetic behaviour of the ferric oxide core.
