Fig. 15From: Recent advances in chiral nanomaterials with unique electric and magnetic propertiesCopyright 2015 Nature Publishing Groupa, b 3D TEM tomography of a LH and b RH single twisted nanoribbons. Scale bars, 100Â nm. c, d SEM images of c LH and d RH single twisted nanoribbons. Scale bars, 500Â nm. e Distributions of LH, RH and non-twisted nanoribbons yielded after 50Â h illumination under RCP, LCP, unpolarized light, linearly polarized light, and in the dark. f CD spectra (solid line) and g-factors (dotted line) of LH and RH twisted nanoribbons obtained after 50Â h illumination. g, h Models of chiral NPs (g) and chiral NP clusters (h) used in calculations of the chiroptical properties. i, j Simulated spectra and g-factors for chiral NPs and chiral NP clusters.
