摘要

水热合成磁性光致发光cufe2o4 -碳点纳米复合材料作为检测Hg(II)离子的传感器，以乙二胺和柠檬酸为材料制备了碳量子点。采用微波合成铁氧体铜，水热法是制备优先生长产物的有效方法。最后合成了CuFe2O4和磁性铁氧体铜-碳纳米复合材料。考察了功率和循环次数对形貌和粒度的影响。采用x射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱(FT-IR)、紫外可见(UV-Vis)吸收和光发光光谱(PL)对纳米结构进行了表征。制备的产物在紫外线照射下具有良好的光致发光性能。振动样品磁强计(VSM)显示了CuFe2O4和铁酸铜-碳纳米复合材料的铁磁性。结果表明，该方法制备的磁性发光纳米复合材料可作为传感器应用的候选材料。关键词:碳量子点;纳米复合材料;磁性;光致发光

Hydrothermal synthesis of magnetic and photoluminescence CuFe2O4-carbon dots nanocomposite as a sensor for detecting of Hg(II) ions

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
