This final project provides a review of the literature on nanoparticle synthesis methods. Silver nanostructures in recent decades have received a lot of attention due to the resonant properties of plasmons. They can be applied in surface enhanced Raman scattering spectroscopy, sensors technologies. The chemical method of nanoparticle formation using polyols, synthesis kinetics and nanocrystal growth mechanism are discussed in more detail. In this work, silver nanostructures were synthesized by chemical synthesis in a polyhydric alcohol (polyol) medium. Compared to physical nanoparticle formation methods, synthesis using polyols is very simple and does not require complex equipment and time. Nanostructures of various sizes and shapes were synthesized using 1,5-pentanediol in the synthesis. The predominant form was cubic in most cases, but other forms of nanostructures, such as nanoprisms, nanospheres, nanowires, were also observed. The optical properties of these nanodevices were investigated. It was found that the growth, size and shape of nanostructures differ when synthesizing nanostructures at different temperatures (125–155 ° C) and using different amounts of copper chloride (20–60 μl). |
