Abstract
Anisotropic plasmonic responses on oblate spheroidal shape were investigated using chemically synthesized gold nanospheres. By employing the polarized transmission spectroscopy with oblique incidence, we observe 12-nm blue shift of the plasmonic resonant wavelength for gold nanospheres. The gold nanospheres with 3-nm deformation exhibited anisotropy by adsorbing on a substrate surface, resulting in the blue shift of plasmon resonant wavelength. The good agreement in measured and simulated transmission spectra leads to a precise design of gold nanospheres for plasmonic applications.
