Abstract:

Metal nanostructures have unique properties that differ from their bulk structures. Among the various silver nanostructures, silver nanoplates have attracted considerable attention because of their shape-dependent optical properties, which have many applications in fields, such as ionic sensing, coloration, surface enhanced Raman spectroscopy (SERS), surface-enhanced fluoroscopy, and biomedicine. We began with the synthesis methods of silver nanoplates, and then gave a brief overview of the research advances of silver nanoplates, including the synthesis methods of silver nanoplates and the influence of experimental conditions, such as illumination, surfactant, and reducing agent, on the morphologies of the products. Then, we summarized the shape-dependent optical property and some important growth mechanisms of silver nanoplates. Finally, we introduced some potential applications of silver nanoplates, followed by summary and outlook for the research in the field.

Key words: Silver nanoplate, Synthesis, Optical property, Growth mechanism, Stacking fault
