Computational studies on the optical properties of nanorods with unique compositions and exotic surface structure are presented. The distinctive architectures investigated-and compared to smooth Au rods-include Ni/Au multiblock rods and nanoporous Au rods. The surface plasmon resonances are extremely dependent upon the morphology and makeup of the nanorods. For a rod with a given aspect ratio, the resonance structure is sensitive to attributes such as the size of Ni sections of multiblock rods and pore structure of nanoporous rods. These studies indicate that control of the optical properties of nanorods is possible via characteristics other than the aspect ratio and suggest that a broader range of tunability is attainable.
