Problems solved by technology

[0003] At present, most of the research on optics focuses on the development of new materials by utilizing the characteristics of the hole array of the alumina membrane, but there are relatively few studies on the physical properties of the alumina membrane itself, especially in the color regulation of porous alumina, and There is no systematic and effective solution, which restricts the function of porous alumina in the visible spectrum range, and thus greatly limits the application of porous alumina in many optical aspects.

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...

Abstract

The invention discloses a color regulation and control method based on porous alumina and single atom deposition technology, which comprises the following steps of: deducing a calculation formula according to a simulated porous alumina membrane system; calculating by the wavelength corresponding to the regulation and control color to be expected to obtain a template hole depth matched with the wavelength; then, preparing a porous alumina template with the required hole depth by accurately controlling the secondary anode oxidation time in the porous alumina preparing process; and depositing a high-reflectivity nano-membrane layer on the surface of the porous alumina template by utilizing the single atom deposition technology to enable the template to present the expected regulation and control color, thereby realizing the regulation and control on the color of porous alumina. The method disclosed by the invention greatly improves the dichroism of the porous alumina used as a two-dimensional photonic crystal, can be used for preparing porous alumina with different regulation and control colors, and realizes the regulation and control on the colors of the porous alumina. The method is hopeful of playing a great role in micro-device preparation in related instruments such as lasers, integrated optical circuits, optical communication instruments, optical interconnection instruments, optical calculation instruments, optical information processing instruments and the like.

Description
