Abstract
Copper doped ZnO nanoparticles were synthesized by the chemical technique based on the hydrothermal method. The crystallite structure, morphology and size were determined by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM) for different doping percentages of Cu{sup 2+} (1-10%). TEM/SEM images showed formation of uniform nanorods, the aspect ratio of which varied with doping percentage of Cu{sup 2+}. The wurtzite structure of ZnO gradually degrades with the increasing Cu{sup 2+} doping concentration and an additional CuO associated diffraction peak was observed above 8% of Cu{sup 2+} doping. The change in magnetic behavior of the nanoparticles of ZnO with varying Cu{sup 2+} doping concentrations was investigated using a vibrating sample magnetometer (VSM). Initially these nanoparticles showed strong room-temperature ferromagnetic behavior, however at higher doping percentage of copper the ferromagnetic behavior was suppressed and paramagnetic nature was enhanced.
