Optical analysis of the small AgAuPt and AuPt NPs fabricated with the Ag8.25nm/Au2.25nm/Pt2.25nm tri-layers. (a) – (a-3) Extinction and normalized extinction spectra. (b) Reflectance spectra. (c) – (c-3) Transmittance and normalized transmittance spectra. (d) and (e) AFM images of typical AgAuPt and AuPt NPs chosen for FDTD simulation. (d-1) and (f-1) Cross-sectional line profiles across the NP in (d) and (f). (e) and (g) E-field distribution in xy-plane. (e-1) and (g-1) E-field distribution in xz-plane.
