Abstract
The characteristics of surface plasmon polariton on metallic nanostructure relate to which of materials, shape and size. So the preparation of SERS-active substrate is the key. In this paper, the silver nanostructure of different shapes was prepared through reduction method of nitric acid silver ion with the polyols. Through the method, the nanostructure has certain crystal and smooth surface, and unique optical properties. Comparing the SERS of the different shape nanoparticles, the inerratic and uniform nanoparticles can improve the effect more. Thus, the comparison results were simulated by three dimensional finite difference time domain (3D-FDTD) method. The result provided experiment basis to the preparation of SERS-active substrate.
