Research data supporting "Tailoring ultrahigh index plasmonic combinatorial metamaterials for SEIRA and SERS by tuning the fill fraction"


Change log

Description

This dataset contains raw spectral data for each main and supplementary figure of a publication showing tunable high refractive index combinatorial metamaterials for surface-enhanced infrared absorption (SEIRA) and Raman spectroscopy (SERS). The SEIRA and IR data are all referenced to a gold mirror and measured in reflection mode, using 200 scans per measurement. The dark field (DF) scattering data is referenced to a white light scattering target and has been background subtracted to remove dark counts. Simulations are carried out with COMSOL and their results tabulated. The dataset includes simulations of the metamaterial as an effective medium with changing geometrical parameters, SEIRA, SERS and DF characterisation of the metamaterial using different fill factors and the substrate's application for enhanced sensing of polystyrene nanoparticles.
