Abstract

Optical properties of metal nano-materials is based on the shape, In this paper, firstly, relationships between scattering efficiency and the incident light wavelength of iron nanoparticles with diameter of 20nm, 40nm, 60nm, 80nm, 100nm were calculated with Mie plot and DDA. The results show that DDA algorithm and program design and parameter settings are accurate. Then scattering efficiency of iron nanorods is calculated by DDA, diameters are 10nm, 20nm, 30nm with different aspect ratio and different incident light wavelength, and relationship between aspect ratio and the scattering efficiency is also analysed. This work will contribute to the exploration of the other optical properties of iron nanorods, and provide the theoretical basis of application.
