Abstract
ZnO DMS were prepared by co-precipitation method. Single phase Zn0.90Co0.05Ni0.05O was confirmed by powder X-ray diffraction (XRD). The samples were characterized by EDS to confirm the expected stoichiometry. SEM revealed no surface precipitation of dopants. Photoluminescence for pure ZnO was observed in the bluish green region. Compared to undoped ZnO, the luminescence of Co–Ni co-doped ZnO was strongly quenched. The samples were examined for its magnetic property using vibrating sample magnetometer (VSM) which indicated ferromagnetic behavior at room temperature with a coercivity of 123.37 g. XRD measurements showed impurity phase for samples prepared by ceramic method.
