Abstract

Using numerical simulations, we demonstrate that fine shape details of gold nanoring-disks are responsible for significant modifications of their localized surface plasmon properties. The numerical results are supported by optical transmission measurements and by atomic force microscopy. In particular, we found that, depending on the ring wall sharpness, the spectral shift of the ring-like localized surface plasmon resonance can be as large as few hundred nanometers. These results shed the light on the strong sensitivity of the surface plasmon properties to very small deviations of the ring and disk shapes from the ideally flat surfaces and sharp edges. This effect is particularly important for tailoring the surface plasmon properties of metallic nanostrutures presenting edges and wedges for applications in bio- and chemical sensing and for enhancement of light scattering.

Experimental (dots) and calculated (lines) spectra of the NRD240 (red) and NRD280 (blue) nanoring-disk samples. The BEM simulations assume perfect ring-disks with NR and ND showing flat surfaces and sharp edges. The scale in the range 400–800 nm is multiplied by a factor of 4.

Model profiles of ring-disks (a) with flat surfaces and sharp edges, and (b) with rounded surfaces and smooth edges.

Fig. 4

Extinction spectra of NRD280 (a) and NRD240 (b) calculated for the various profiles of the ring-disks shown in the insets (only half the ring-disk is sketched). The spectrum corresponding to each profile is color-encoded. The profiles of the perfect ring-disks with sharp edges and flat surfaces and the corresponding spectra are shown in black dashed lines. The measured optical density spectra [OD = −log(T)] are plotted with black dots. The inset in panel (a) shows the relative LSPR shift Δ λ / λ LSPR ideal as a function of the relative deviation of the mean NR wall thickness (w − 〈w〉)/w.

Top part of the average AFM topography profiles (green lines) and of the model ring-disk profiles having both flat surfaces with sharp edges (black dashed lines), and rounded surface with smooth edges (blue dashed lines) for both samples NRD280 (a) and NRD240 (b). For NRD240, a profile with hNR =25 nm< hND =28 nm is also shown in red dashed line.

All the upper panels show a side view at y = 0 and all the lower panels show a top view at z = h/2 = 14 nm of the calculated nearfield distributions for both sharp (a, c) and rounded (b, d) ring-disks (NRD240) associated to both disk-like (a, b) and ring-like (c, d) LSPRs. Panel (e) shows the nearfield distribution around the rounded ring-disk (NRD240) excited in resonance with the ring-like LSPR of the sharp ring-disk. The white arrow indicates the polarization of the incident field E⃗i which propagates along the z-direction. The color scale refers to the field enhancement factor |E⃗loc|/|E⃗i|.
