Francis, R. Saravanan, L. Berchmans] In this study, Co-doped Zn1−x Co x O (x=0.04, 0.06, 0.08, and 0.10, where x is the concentration of guest atom cobalt in the ZnO lattice) bulk samples were examined to determine the effect of doping on electronic, structural, magnetic, and optical properties. The samples were prepared using a standard high-temperature solid-state reaction technique. All samples were characterized by x-ray diffraction (XRD), magnetization measurements using vibrating-sample magnetometry (VSM), optical absorption spectroscopy, and scanning electron microscopy (SEM) with energy-dispersive x-ray spectroscopy (EDAX). The electron densities derived from the maximum-entropy method (MEM) show an improvement of electronic charge densities with Co impurity addition. The magnetic measurements at room temperature show variations in ferromagnetic behavior with respect to Co addition. The optical study shows a decrease in energy gap of ZnO with increasing cobalt content.
