Optical characteristics of the fabricated PCE_R: (a) Photograph of the fabricated PCEs under white backlight. (b) CIE chromaticity diagram. The measured colors correspond to the following (x,y) points: (0.4904, 0.3391) for PCE_R, (0.4281, 0.4666) for PCE_G, and (0.2915, 0.3080) for PCE_B; (c) Transmittance spectra of the simulated and fabricated PCEs; (d) Focused-ion-beam scanning electron microscope (FIB-SEM) image. Insets show surface images of the photo-resist layer after the developing process (left) and a surface image of the Al layer after LIL (right). All of the scale bars in (d) are equal to 500 nm.
