Abstract: One of the new applications of silver nanoparticles is their use in plasmon applications, which are determined by the strong interaction between the electromagnetic wave and free electrons in nanostructures. Particles of a metal with a size smaller than the wavelengths of visible light can strongly absorb light due to the phenomenon of surface plasmon resonance, due to the collective oscillation of conduction electrons. The frequency and intensity of the plasmon resonance depends on the distribution of the polarization charge in the nanostructure, which, in turn, is determined by the shape and structure of the nanoparticle. Thus, control of the structure of the metallic nanostructure allows you to control the wavelengths of light that it dissipates and absorbs.
Keywords: nanoclusters, silver, structure, computer simulation, tight-binding.
