Paper Abstract

This work reported a preliminary study of doped ZnO nanoparticles by fine optical group-IB element Ag as the foundation to achieve p-type conduction of ZnO. Ag-doped ZnO nanoparticles were synthesized under lower temperature by annealing treatment in water-soluble silicone oil to the precursor [Zn(OH)4]2- with Ag+ prepared in a quaternary reverse micro-emulsion. The products were characterized by X-ray diffraction (XRD), Transmission Electron Microscope (TEM), UV-visible spectroscopy and photoluminescence spectra (PL). The influence of Ag doping level on the optical properties of ZnO nanoparticles was studied and the photoluminescence mechanism was analyzed. The origin of relative variety of near band edge emission (NBE) and deep level emission (DLE) of ZnO in virtue of incorporated Ag+ was discussed. The value of OH-/Zn2+ in precursor and annealing temperature also effected the optical properties of Ag doped ZnO. The optimum conditions were given for preparation of Ag-doping ZnO nanoparticles.
