Synthesis and Structural Properties of Pure and co-doped (Cu, Ag) ZnO Nanoparticles

摘要

Pure ZnO and co-doped (Cu, Ag) ZnO nanoparticles (Zn_(0.90)Cu_(0.05)Ag_(0.05)O) are synthesized by chemical co-precipitation method in the presence of capping agent polyethylene glycol 600 (PEG 600) and annealed at 500 °C for 1h. The XRD measurements indicate that the samples show hexagonal structure without any change and the nanocrystalline size decreased from 12 to 5 nm. SEM images are of hexagonal structure of the ZnO and co-doped ZnO samples, and EDAX spectra reveals that the successful doping concentration of Cu and Ag.
