Structure analysis on Ni and V co-doped zinc oxide prepared by solid state reactions

摘要

Powder samples of ZnO co-doped with Ni and V have been grown by standard solid state reaction technique with varying concentrations 2, 4 and 6 %. The grown samples were found to be dilute magnetic in nature along with semiconducting property. The structure of the grown material was solved using powder X-ray diffraction refinements and the electronic structure of the material was determined by maximum entropy method. Magnetic properties of the samples were studied using vibrating sample magnetometry and the samples exhibited ferromagnetic characteristics at room temperature. Inductively coupled-atomic emission spectroscopy was employed to identify the elemental composition of the grown samples. Direct band gap of the material was calculated using UV-vis studies.
