Size-Dependent Localized Surface Plasmon Resonance of Large Triangular Ag Nanoprisms

Abstract

This paper is devoted to the study of dependences of the optical characteristics of large triangular silver nanoprisms on its geometrical parameters. Simulation of the position of localized surface plasmon resonance peaks for triangular silver nanoprisms was performed using the discrete dipole approximation approach in NanoDDSCAT software. It has been shown that the optical characteristics of triangular nanoprisms depend on its size parameters: edge length and thickness.
