Structural, morphological and magnetic properties of Zinc oxide, Strontium doped Zinc oxide, Strontium copper codoped Zinc oxide, and Strontium nickel codoped Zinc oxide nanoparticles synthesized by co-precipitation method

Abstract

Zinc oxide (ZnO), Strontium doped Zinc oxide (Sr:ZnO), Strontium copper codoped Zinc oxide (SrCu:ZnO), and Strontium nickel codoped Zinc oxide (SrNi:ZnO) nanoparticles (NPs) were synthesized through co-precipitation method. The XRD results confirmed the hexagonal wurtzite structure for ZnO, Sr:ZnO, SrCu:ZnO and SrNi:ZnO NPs. The FESEM image showed the spherical, spherical, spherical and trigonal structure ZnO, Sr:ZnO, SrCu:ZnO and SrNi:ZnO NPs. Chemical composition was identified by EDAX spectra. Magnetic measurements using VSM showed that the Sr:ZnO, SrCu:ZnO and SrNi:ZnO NPs exhibits ferromagnetic behaviour at room temperature.
