Abstract:

The ZnO-Ag core-shell nanoparticle in ethanol was prepared by photoreduction and colloidal methods. The experimental results obtained from the absorption spectrum, fluorescence spectrum and electron microscopy revealed that the structure of the hybrid particle is ZnO core covered with Ag. The thickness of silver layer formed on ZnO core can be controlled by the concentration of Ag+ and the time of UV irradiation. In addition, the electrical properties of the charge double layer of the ZnO particle greatly affect the formation of ZnO-Ag hybrid particle.
