Theoretical study on surface plasmon properties of gold nanostars
With the rapid development of nanotechnology,the surface plasmon properties of metal nanostructures have become the focus of research.In this paper,a multi-tip gold nanostars(GNSs)structure is designed theoretically,and its surface plasmon properties are simulated by using the finite element method(FEM),which is practical and versatile.Compared with the traditional spherical and triangular plate particles,the results show that the tip structure of the GNSs has a stronger hot spots effect,resulting in greater local field enhancement properties.The relationship between the structure parameters of GNSs and their resonance peaks was also studied.The results indicate that the resonance peaks of GNSs depend strongly on the size,spacing between two GNSs,quantity and refractive index of the GNSs.
