Abstract

We have experimentally examined the effect of all dielectric metasurface's localization in plasmonic hot spots over the two dimensional periodic structure onto the laser induced fluorescence. The host medium of the dye achieved by spin coating of the Rh6G over the two dimensional MgF2/Gold structure and the LIF signal records in visible region by nanosecond Green laser pumping. Our results indicate that the localized field enhancement due to Electric and Magnetic dipoles resonance of all dielectric media and also refractive index localization effect can boost laser induced fluorescence in the visible region until 5 times in the comparison with the sample without bottom dielectric layer.
