Multi-scale Computational Visualization of Angle-dependent and Roughness-sensitive Plasmonic Structural Coloration

摘要

Figure 1: (a) Schematic diagram and (b) cross-section view of a unit cell FDTD simulation 20-nm-thick silver nanohole array of coated on glass substrate. (c) Spectral reflectance and (d) transmittance of 20-nm-thick silver nanohole array with a smooth profile and 5 distinct surface roughness profiles (colored lines). (e) Rendered images of smooth and rough silver nanohole arrays coated on spherical substrate in reflectance (second row) and transmittance (third row). The associated color difference, ∆E00, as shown in reflectance (first row) and transmittance (last row). Click the link to preview the plasmonic structural color coated on 3D objects: Link.
