Copper-doped ZnO nanoparticles were synthesized by the sol-gel method.The X-ray diffraction(XRD) result shows that Zn1-xCuxO(x≤0.04) samples are single phase with ZnO-like wurtzite structure,while the secondary phase Cu is observed in a Zn0.95Cu0.05O sample.Magnetic measurements indicate that Zn1-xCuxO(x≤0.04) samples are ferromagnetic at room temperature.A strong green peak(520 nm) was observed except for UV band peak in photoluminescent(PL) spectrum of Zn0.98Cu0.02O.
Copper-doped ZnO nanoparticles were synthesized by the sol-gel method. The X-ray diffraction (XRD) shows that Zn1-xCuxO (x≤0.04) samples are single phase with ZnO-like wurtzite structure, while the secondary phase Cu is observed in a Zn0.95Cu0.05O sample. Magnification measurements that that Zn1-xCuxO (x≤0.04) samples were ferromagnetic at room temperature. A strong green peak (520 nm) was observed except for UV band peak in photoluminescent (PL) spectrum of Zn0.98Cu0.02O.
