US Patent 8088484 - Metallic nano-chain photodetector


This patent teaches a new type of nanostructured photosensor based on the plasmon resonance absorption effect which provides improved wavelength selectivity. Claim 1 reads:

1. A metallic structure comprising a metallic nano-chain with plasmon resonance absorption,

wherein the metallic nano-chain is formed of a plurality of metallic nanoparticles mutually linked with a plurality of bottlenecks; and

each of the metallic nanoparticles is formed in any one of a circular shape, a triangle shape, and a rhomboid shape.
