Abstract
Hydrothermal synthesis of magnetic and photoluminescence CuFe2O4-carbon dots nanocomposite as a sensor for detecting of Hg(II) ionsCarbon 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 microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, ultra violet-visible (UV-Vis) 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.Keywords: Carbon Quantum Dots; Nanocomposite; Magnetic; Photoluminescence
