| Abstract: | A simple sonochemical technique was used to synthesize gold nanoparticles at room temperature.The reaction based on chemical reduction of HAuCl4by ethylene glycol plus Polyvinyl pyrrolidone(PVP) as dispersant and protectant.The prepared Au nanoparticles were highly dispersed and uniform in size(with average size of about 10nm). |
