The prepared nanoparticles were characterized with X-ray diffraction (XRD). The XRD patterns show the pattern of typical ZnO nanoparticles and correspond with standard XRD pattern as given by the Joint Committee on Powder Diffraction Standards (JCPDS) card no. 36-1451 showing hexagonal phase structure. Luminescence properties are discussed by probing the Photoluminescence properties of undoped zinc oxide (ZnO) nanoparticles as well as ZnO nanoparticles doped with Magnesium at different doping concentrations Wed, 01 Jan 2014 00:00:00 GMT http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/842 2014-01-01T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/841 Title: Magnetic properties of Zn1-xCoxO nanoparticles. Authors: Singh, N.S Abstract: Zn1-xCoxO nanoparticles have been synthesized at various concentrations of Co2+ doping (0.005 􀂔 x 􀂕 0.15) by wet chemical method. Particle size was ranging from 34 – 45 nm. The magnetic moment increases from x = 0.005 and 0.01 sample to x = 0.04 sample drastically showing a value of magnetic moment as high as 8.54 􀈝B/Cations and then decreases for x = 0.09 and 0.15 values of Co2+ doping. There is almost paramagnetic behaviour for x = 0.005 and 0.01 Co2+ doped samples. The x = 0.04 sample shows ferromagnetic ordering. Ferromagnetic behaviour decreases for x = 0.09 and 0.15 samples as the antiferromagnetic interaction dominates at higher Co2+ doping concentrations. To probe the source of magnetism we have undertaken photoluminescence studies also which revealed the presence of oxygen and Zinc vacancies along with other defects..
