Abstract: Mg-doped ZnO nano-plates were successfully prepared by the low cost wet chemical method. X-ray diffraction (XRD) pattern revealed a polycrystalline pure hexagonal wurtzite structure. Scanning electron microscopy (SEM) was used to study the morphology of the synthesized samples. Further, Energy-dispersive X-ray spectroscopy (EDS) measurement confirmed the presence of Mg elements in the ZnO matrix. The UV-visible reflectance spectroscopy was applied to study the effect of dopant on band gap of pure ZnO. The result showed a slight decrease in the band gap with Mg doping. In addition, the dielectric analyses of the obtained samples were done in a wide frequency range and electronic properties of the pure and doped samples were analyzed using various theoretical models. These results suggested that the Mg-doped ZnO nano-plates have potential applications in the optoelectronic devices. The results were analyzed in derail. (C) 2014 Elsevier Ltd. All rights reserved.
