dc.description.abstract | We present theoretical and experimental studies on the optical properties of dimers composed of octahedron-shaped, gold nanoparticles. The experimental measurements show that the photoluminescence varies quite dramatically as two octahedra are brought into close proximity. AFM images and optical emission have been recorded for dimers in uncoupled and strongly coupled configurations. The former displays a single emission peak, while the latter shows two peaks with the new feature at longer wavelengths. Calculations indicate that the red-shifted peak originates from a strongly coupled plasmon state that oscillates along the extended axis of the dimer. Theoretically, we investigate the distances over which the dimers couple and find this to be particularly plasmon mode dependent. The anisotropic morphology and sharp apexes contribute significantly to the orientational dependence of the interparticle couplings and field properties. | - |
