hydrothermal synthesis of magnetic and photoluminescence cufe2o4-carbon dots nanocomposite as a sensor for detecting of hg(ii) ions

Carbon quantum dots were prepared by using ethylene-diamine and citric acid materials. micro-wave was applied for synthesis of copper ferrite, hydrothermal method was used as an effective method for preparation of product with preferential growth. finally, cufe2o4 and magnetic copper ferrite-carbon nanocomposite were synthesized. the effects of power and cycles on the morphology and particle size were investigated. nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microsco-py (tem), fourier transform infrared (ft-ir) spectroscopy, ultra violet-visible (uvvis) absorption and photo-luminescence (pl) spectroscopy. the prepared product show suitable photo-luminescence under ultraviolet irradiation. vibrating sample magnetometer (vsm) shows ferromagnetic property of the both cufe2o4 and copper ferrite-carbon nanocomposite. the results show that this method for preparation of magnetic and luminescence nanocomposite as a candidate for sensor applications.
