Plasmon Coupling in Dimers of Au Nanorods
The coupled plasmon absorption of Au nanorod dimers is investigated as a function of the orientation between the long-axis of the nanorod by linking them with rigid and flexible molecules. As the angle between the Au nanorods increases, the coupled plasmon hand shifts to longer wavelength confirming the role of effective dipolar overlap.
