Keywords:metasurface, plasmon, plasmon enhancement

Fluorescence enahncement by plasmonic strucutres has been reported mostly on the wavelengths from 550 to 850 nm, and has hardly been reported on the range more than 1000 nm. We here report our experimental results on enhancement effect for NIR dye molecules using resonance-tunable metasurfaces with plasmon-photon hybrid resonances.
