Abstract

A facile two-steps method for preparation of the Fe3O4/ZnSe nanocomposite at room temperature has been reported. The prepared samples were characterized by XRD, SQUID VSM, Mössbauer, UV-vis and Photoluminescence (PL) spectroscopy. Zero-field-cooled (ZFC) and field-cooled (FC) measurements show irreversibility up to room temperature and a superparamagnetic blocked state below 250 K. Mössbauer spectra at RT shows typical relaxed sextet pattern with a superparamagnetic doublet. PL spectra show strong near band edge emission and some weak peaks related to different defects levels.
