Various Applications of the FLPR Sensors

Caption

Various applications of the First-order lattice plasmonic resonance (FLPR) a) Spectral response of the nanovoid array SP sensor caused by injection of saturated ethanol vapour. (b) Squared normalised EM-field amplitude E2/E2 0 calculated near the surface of the nanovoid array immersed in toluene, upon its excitation from the top by a linearly-polarised source at a 2.5-μm wavelength. (c) FTIR reflection spectra of the nanovoid array in air and under the toluene liquid layer. The dashed curve provides the contribution of the nanovoid array to the reflection spectrum, if taken without the absorption of toluene. The bottom panel shows the FTIR reflection from the smooth Au film surface covered by toluene obtained under the same conditions.
