Abstract

In this paper, the research objects are the spherical and rod-shaped Ag nanoparticles at quantum scale. Their absorption and scattering properties are modelled and analyzed by numerical simulation. The results show that, compared with the calculated results of classical model, the absorption peak positions of the modified electromagnetic model have moved significantly, and the values of the peaks have been significantly reduced. The absorption peak of the rod-shaped Ag nanoparticles can be effectively optimized to the visible light band and a higher absorption factor value.
