Embodiment Construction
[0018] The color control based on porous alumina and single atom deposition technology is mainly realized by regulating the pore depth of the porous alumina template. The desired tuned color and pore depth of the porous alumina template prior to single-atom deposition also corresponded to each other.
[0019] Such as figure 1 As shown, the steps of the color regulation method based on porous alumina and single atom deposition technology are as follows:
[0020] 1) by the wavelength corresponding to the expected control color on the chromaticity diagram, according to the simulated structure, calculate the pore depth of the porous aluminum oxide film corresponding to it;
[0021] 2) After degreasing the aluminum foil with a purity of 99.999% in acetone and ethanol, at a high temperature of 500°C, 2×10 -5 Annealed in torr vacuum environment for 5-6 hours, in HClO with a volume ratio of 1:3 4 :C 2 h 5 Electrochemical polishing was carried out in OH polishing solution to obta...
