摘要: Structural colours have received a lot of attention regarding the reproduction vivid found in nature. In this study, metal-anodic aluminium oxide (AAO)-Al nanostructures were deposited using two-step anodization and sputtering process to produce self-ordered anodic films metal layer (8 nm Cr 25, 17.5 10 Au), respectively. AAO different thickness anodized Yxy values (Y is luminance value, x y are chromaticity values) obtained via reflectance measurements. An empirical model based on porosity was determined, which describes gamut colours. The proposed mathematical can be applied fields, such as wavelength absorbers, RGB (red, green, blue) display devices, well chemical or optical sensors.
