Fig. 4: Luminescence difference spectra for metafilms.
From: Controlling the symmetry of inorganic ionic nanofilms with optical chirality
a, c show the difference in luminescence RCP–LCP for the LH nanostructure (red), RH nanostructure (blue) and equivalent unstructured surface (black). The LH and RH structures show opposite differences at the 7F2 peak. The width and spacing labels equate to the lateral size and interstitial spacing of the nanostructures, respectively, ΔIERCP − ΔIELCP values for each handedness of structure are shown (red and blue for LH and RH structures, respectively), demonstrating the same equal and opposite behaviour as the difference spectra. Insets show structure geometries not drawn to scale (see Supplementary Fig. 3 for scale diagrams).
