Measured and calculated reflectance spectra using FDTD with the anionic layer model, with and without absorption. a d _int = 100 nm and b d _int = 440 nm. The red dots represent the measured reflectance spectra, the green dashed line the FDTD result for the anion layer model without absorption and the blue solid line the FDTD result for the anionic layer model with absorption
