‘Reversed Turkevich’ method for tuning the size of Gold nanoparticles: evaluation the effect of concentration and temperature |
|
| چکیده انگلیسی مقاله |
In this study the influence of dicarboxy acetone (DCA), as an oxidation product of sodium citrate, was evaluated by 'reversed Turkevich' method in this study. Gold nanoparticles (GNPs) were synthesized systematically at various sodium citrate to HAuCl4 molar ratio and temperature. TheseThe GNPs were characterized by UV-vis spectroscopy, DLS and TEM techniques. The results showed that by reversing the order of reagents addition we could synthesize GNPs were obtained in range of 12-51 nm. All of these GNPs samples were monodisperse and have had the same pattern of narrow size distribution in contrast to traditional Turkevich method in which GNPs larger than 40 nm became unstable. Moreover, Sodium citrate to HAuCl4 molar ratio and temperature had a significant role in size controlling and monodispersity of GNPs. By increasing sodium citrate to HAuCl4 molar ratio,s the size of GNPs reduced drastically. Since, temperature had a central role on the production rate of DCA, so its influence on monodispersity of GNPs was more considerable than the size of them. |
