摘　　要：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） 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.
