Generally, several metal nanoparticles(MNPs) and quantum dots(QDs) are produced by reduction of metal ions. In this study, we use dendritic polymer, for example polyethyleneimine, as stabilizing agent. Dendritic polymer play an important role in stabilization of metal ions. We developed a method to prepare size-controllabled MNPs and QDs by varying concentration ratio of metal ion solution, stablition agent and reduction agent. We observed an absorption curve around each range of MNPs in UV-vis absorption spectroscopy. Our attempt of this method on Au, Ag and Cd produced nanoscaled particles by DLS experiment. This strategy to get a low dispersity and size controlled MNPs and QDs. Transmission electron microscopic(TEM) measurements indicated the presence MNPs and QDs. We developed this strategy to get low dispersity and size controlled MNPs and QDs. |
