  • Publication number: 20060274315
    Abstract: The electric-field enhancement effect by plasmon resonance is improved by favorably controlling the plasmon resonances in the thickness direction and in the direction orthogonal thereto. The plasmon resonance structure body comprises alternately stacked layers of metal nanoparticle layers and dielectric particle layers. The metal nanoparticle layers have a structure as such that the nano-sized fine particles of Au, Ag, Al, or the like, form metallic domains disposed at proper distance from each other along the direction orthogonal to the stacking direction of the layers. Used as the dielectric particle layer is, for instance, SiO2. The plasmon resonance in the thickness direction of the direction orthogonal thereto of the plasmon resonance structure body can be controlled by changing the particle diameter or the distance among the particles of the metal nanoparticles and the dielectric particles, or by changing the number of the stacked layers.

    Abstract: Metallic particle layers with metallic domains being arranged therein each at a predetermined space within a horizontal plane are laminated at an appropriate distance in the vertical direction in a dielectric layer. The distance ?W between each of the metallic domains may be controlled by controlling the growth of metallic particles for the horizontal direction and the distance ?L between the metallic particle layers may be controlled by controlling the thickness of the dielectric layer to be laminated for the vertical direction, so that the effect of field enhancement by plasmon resonance is improved by satisfactory control for the plasmon resonance in the direction of the thickness and in the direction orthogonal thereto.
