Hybrid Ni/SiO2/Au dimer arrays for high-resolution refractive index sensing

Hybrid Ni/SiO2/Au dimer arrays for high-resolution refractive index sensing

We introduce a novel magnetoplasmonic sensor concept for sensitive detection of refractive index changes. The sensor consists of a periodic array of Ni/SiO2/Au dimer nanodisks. Combined effects of near-field interactions between the Ni and Au disks within the individual dimers and far-field diffract...
