Preparation and Characterization of ZnO and Mg-ZnO nanoparticle

摘要

ZnO is one of the most promising materials since it has a high mechanical and thermal stability, and wide band gap (3.37 eV). Meanwhile, doping with selective elements offers an effective method to enhance and control the electrical and optical properties of ZnO nanostructures, which is crucial for its practical applications. Mg-doped ZnO have considerable interests owing to their unique optical, electric and piezoelectric properties. In this paper, we report the Synthesis of Mg-doped ZnO nanoparticles successfully with diameters ranging from 50 to 100 nm via precipitation method. The surface morphology of synthesized material was investigated by using scanning electron microscope (SEM) and the elemental analysis by energy-dispersive X-ray spectroscopy (EDAX). The presence of Mg was confirmed by infrared spectroscopic (IR) studies. The structure and phases of Mg-ZnO were analyzed by powder X-ray diffraction (XRD) method and the Optical properties were measured by using UV–Vis spectrophotometer.
