Transmissive/Reflective Structural Color Filters: Theory and Applications
Figure 4
(a) Transmission spectra of color filters based on cross-shape nanohole array in the visible band. (b)–(d) are the transmission spectra versus incident angle . The geometrical parameters as defined in Figure 3(a): nm; nm (blue), 140 nm (green), and 180 nm (red); nm (blue), 50 nm (green), and 40 nm (red); nm (blue), 180 nm (green), and 230 nm (red).
