  • Optical electric field enhancement element and probe using the same
    Patent number: 8601610
    Abstract: An optical electric field enhancement element includes a nanorod which includes a plurality of conductive layers formed therein in a direction parallel to a longitudinal axis of the nanorod. Adjacent conductive layers are isolated from each other via an insulating layer. The nanorod exhibits an effect of enhancing an optical electric field.

  • OPTICAL ELECTRIC FIELD ENHANCEMENT ELEMENT AND PROBE USING THE SAME
    Publication number: 20100281587
    Abstract: The optical electric field enhancement element of the invention comprises a nanorod where a conductive layer and an insulating layer are laminated. In particular, the optical electric field enhancement element comprising a tungsten oxide nanorod exhibits a high enhancement effect not by an aggregate of fine crystals but by the crystal structure itself, therefore securing good reproducibility and a stable Raman scattering enhancement effect. A sensor comprising the optical electric field enhancement element enables various high-precision analyses heretofore impossible in the art.
