| Abstract: | In this article,the Discrete Dipole Approximation(DDA) was used to calculate the extinction spectra of the gold and silver nanoparticles with the shape of sphere and cylinder.The results showed that the peak place and the strength of the extinction spectra of the nanoparticles with different material were distinct.This research will provide some useful theoretical reference for the applications of the nanoparticles in the fields of photoelectric device and chemistry sensor etc. |
