This review discusses the synthesis and assembly of silver nanostructures for plasmonic applications. Silver is the most important material in plasmonics due to its unique properties, including a wide range of plasmonic resonance wavelengths (300–1200 nm) and high quality factor (Q), which is crucial for strong plasmonic effects. Silver's high electrical and thermal conductivity, along with its ability to form stable nanostructures, makes it ideal for plasmonic applications. However, silver nanostructures can be toxic, and their stability can be improved through surface passivation. Compared to gold, silver offers better performance in plasmonic applications outside the human body, such as in plasmonic antennas and circuits. The review covers various methods for synthesizing silver nanostructures, including chemical reduction, the silver mirror reaction, the polyol process, and seed-mediated growth. The polyol process is particularly effective for producing a wide range of silver nanostructures with controlled sizes and shapes. The synthesis involves the use of polyols as solvents and reducing agents, with capping agents like PVP controlling the morphology. The reaction is sensitive to temperature and trace ions, which can influence the final product morphology. The quality factor (Q) is a key parameter in plasmonic applications, with silver having the highest Q value across the visible and near-infrared spectrum. Seed-mediated growth allows for precise control over the size, shape, and aspect ratio of nanostructures by using pre-formed seeds. This method is versatile and can produce a variety of nanostructures, including cubes, right bipyramids, and pentagonal wires. The growth is influenced by the capping agent, which can control the growth rates of different crystallographic facets. Heteroepitaxial growth, where seeds are chemically different from the deposited metal, can also be used to create complex nanostructures. Light-mediated synthesis is another method for producing silver nanostructures, where light excitation can be used to grow or modify nanostructures in a controlled manner. This method can produce well-defined and controllable shapes, making it a promising approach for plasmonic applications. Overall, the review highlights the importance of controlling the synthesis and assembly of silver nanostructures to achieve desired plasmonic properties and applications.This review discusses the synthesis and assembly of silver nanostructures for plasmonic applications.
