Degenerating Plasmonic Modes to Enhance the Performance of Surface Plasmon Resonance for Application in Solar Energy Conversion

A new approach to enhance surface plasmon resonance (SPR) performance by degenerating the quadrupole and dipole SPR modes of highly ordered Ag nanoparticle arrays is proposed. The degenerate reason is confirmed to originate from the variation of refractive index in different wavelengths. The degenerate plasmonic modes strengthen SPR, which improves the photocurrent and photocatalytic activity in this incorporated system.
