A tunable optical spectrum corresponding to the transverse SPR modes is observed. The peak resonance wavelength (lambda(res)) can be shifted to red as the core patterns in rod-shape MNPs have been changed. We find that the 2D periodic array of core-shell MNP pairs (case 2) exhibit a red shifted SPR that can be tuned the gap enhancement and absorption efficiency simultaneously over an extended wavelength range. The tunable optical performances give us a qualitative idea of the geometrical properties of the periodic array of rod-shape MNP pairs on SPRs that can be as a promising candidate for plasmonic biosensor and solar cell applications. |
