| Abstract: | Seed mediated method is used to control the additions of AgNO3 to prepare Au nanorods with different aspect ratios in bimolecular colloidal solution produced by CTAB and BDAC. Influenced by surface active agents, Au crystal seeds gradually grow in the direction of 100] to form anisotropic nanostructures, while other directions are limited. Based on the experimental results, the finite difference time domain method is employed to simulate the growth of Au nanorods in the background 1.33 of permittivity so as to explore the optical absorption spectra of the Au nanorods. |
