(a) Schematic of the multi-level F–P absorber for highly integrated reflective vivid colour generation. (b) FDTD simulation of the reflectance as a function of the wavelength and HSQ cavity thickness in the Ag-NC-based absorber. (c) Photograph of the absorbers with eight different colours including blue, cyan, green, yellow, orange, magenta, wine, and purple. (d) Measured reflectance spectra of the absorbers with different HSQ cavity thicknesses of 70 to 280 nm.
