Abstract:
We experimentally and theoretically investigate Fano-like resonance in a large-area Au/SiO 2 /Au nano-patches meta-structure, which originates from the coupling between Fabry–Perot resonance and magnetic dipole resonance modes. A highly sensitive refractive index sensor based on the lineshape analysis is obtained. The extracted wavelength shift with the amount of substance of Hg 2+ changing from 10 –3 pmol to 1 nmol has a linear dependence, and the sensitivity can reach to ultra-low limit of detection (LOD) as 10 –3 pmol. This study may provide an approach for the development and modification in sensing.
