Abstract
Silver (Ag)-doped zinc oxide (ZnO) nanoparticles with different compositions, Zn1−xAg x O (x = 0, 0.02, 0.04, 0.06, 0.08. 0.10), were synthesized by a chemical precipitation method. The formation of a single-phase wurtzite hexagonal crystalline structure for doped ZnO nanoparticles has been investigated using x-ray diffraction. The crystallite size of the samples was evaluated by the Scherrer method and the values go on improving with increases in the concentration of dopant. Scanning electron microscopy and energy dispersive spectroscopy have been used for morphology and composition studies. The crystallite size, dielectric properties and alternating current conductivity of undoped ZnO nanoparticles were significantly affected by Ag do**. At high frequencies, the materials showed high dielectric constants and high conductivity. A detailed examination of the conductivity and dielectric loss with composition were studied in a wide frequency range at room temperature. The magnetic properties exhibited ferromagnetism both for the undoped and doped ZnO nanoparticles at room temperature, apart from saturation magnetization (Ms) which increased linearly with dopant concentration. These Ag-doped ZnO nanoparticles can be used in the preparation of spintronic applications.
