Preparation of size and morphology controlled Gold Nanoparticles in Micro-emulsion and in Aqueous
In this study,we prepared gold nanoparticles in micro-emulsion and found the optimum ratio of micro-emulsion for preparing gold nanoparticles.We reported a new stabilizer for preparing gold nanoparticles in aqueous and found the optimum mass ratio between the stabilizer and chlorauric acid.All gold nanoparticles prepared by these two methods were characterized by transmission electron microscopy,ultraviolet-visible spectrophotometer and synchronous light-scattering spectrophotometer.The results of transmission electron microscopy showed that the diameter range of gold nanoparticles prepared in micro-emulsion was 5~10 rim,and that in aqueous was 10~15 nm.They all had homogeneous distribution and dense structures.
