摘要 | Cu-doped ZnO nanoparticles were successfully synthesized and structurally characterized by using X-ray diffraction (XRD) and transmission electron microscope (TEM). XRD shows that Zn(1-x)Cu(x)O (x a parts per thousand currency sign 0.04) samples are single phase with the ZnO-like wurtzite structure, while the secondary phase Cu is observed in Zn(0.95)Cu(0.05)O sample. Magnetic measurements indicated that Zn(1-x)Cu(x)O (x = 0.02, 0.03, 0.04) are ferromagnetic at room temperature and the magnetic moment per Cu atom decreased with increasing Cu concentration. XRD, TEM and X-ray photoelectron spectroscopy (XPS) analysis revealed that no ferromagnetic-related secondary phase was detected. The origin of the ferromagnetism in Zn(1-x)Cu(x)O (x a parts per thousand currency sign 0.04) was mainly due to Cu ions substituted into the ZnO lattice. |
