文摘

Ag-doped and pure zinc oxide (ZnO) nano-plates were successfully synthesized via low cost wet precipitation method. The crystalline phases and the morphological features of the synthesized samples were assessed by X-ray diffraction (XRD) and scanning electron microscopy. These techniques coupled with Energy-dispersive X-ray spectroscopy (EDS) measurements confirmed the incorporation of Ag element into the ZnO matrix. The dielectric loss and ac conductivity were studied as a function of frequency and composition. A detailed analysis of the dielectric loss and ac conductivity as a function of composition were done in a wide frequency range at room temperature. In addition, the charge transport mechanism through the grain and grain boundary regions were investigated using impedance spectroscopy analysis.
