Figure 1

(a) Schematic diagram of proposed reflective RGB structural color filters. (b) Calculated resonant mode number, which is the net phase shift divided by 2π, in the WO3 #1 FP cavity and the WO3 #2 AR layer for the RGB. (c) Measured and simulated reflectance spectra of the reflective RGB structural color filters. (d) Optical images of the fabricated RGB color filter samples. (e) Color coordinates calculated from both the measured and simulated reflectance spectra along with the standard RGB color space (sRGB).
