A Review on Plasmonic-Metal Nanostructures, and their Preparation Methods

Nowadays, metal nanostructures are interested due to their exclusive physical and chemical properties. In this review paper, different shape and size controlled methods for preparation and synthesis of metal nanostructures have been considered. Among these metal nanostructures, silver nanowires due to their plasmonic characteristics and potential applications in optoelectronic devices have been studied significantly. Therefore, here, physical and chemical methods of silver nanowire synthesis are presented in details. Furthermore, new procedures such as double reductant method, etching technique and construction of core-shell nanostructures are introduced. Since the Polyol method is the most successful way to prepare silver nanostructures with well-controlled shapes, this technique was explained comprehensively in this text.
