摘要

Fabrication and surface plasmon properties of gold nanostructures consisting of periodic arrays of disk trimers are reported. Using electron beam lithography, disk diameters as small as 96nm and gaps between disks as narrow as 10nm have been achieved with an unprecedented degree of control and reproducibility. The disk trimers exhibit intense visible and infrared surface plasmon resonances which are studied as a function of the disk diameter and of the pitch between trimers. Based on simulations of the optical extinction spectra and of the electric near-field intensity maps, the resonances are assigned to a single trimer response and to collective surface plasmon excitations involving electromagnetic interaction between the trimers. The sensing properties of the disk trimers are investigated using various coating media. The reported results demonstrate the possible use of gold disk trimers for dual wavelength chemical sensing.
