Method for preparing aluminium oxide nano-form photon crystal

Abstract

A process for preparing photon crystal from aluminium oxide nanotemplate includes such steps as dissolving the oxidized surface layer of Al sheet, and alternatively high-voltage anodizing and low-voltage anodizing more times to generate the periodic variation of aluminium oxide nanostructure on the surface of Al sheet, resulting in periodic pore structure.

Description

technical field [0001] The invention relates to a method for preparing photonic crystals by changing the preparation process of aluminum oxide nanometer templates, which belongs to the technical field of electrochemistry. Background technique [0002] It is well known that nanostructure templates are usually used in the preparation of nanomaterials. Due to the ordered structure of the alumina template, an ordered nanostructure assembly system can be produced, and the preparation of the alumina nano-template is simple and low-cost. Therefore, currently, the alumina template is mostly used to prepare nanomaterials. However, the current methods of preparing alumina nano-templates such as electrochemical deposition, chemical deposition, and vapor deposition can only produce one-dimensional nanotube materials and arrays with controllable length and diameter. These existing preparation methods cannot produce Therefore, it is very likely to limit the application of alumina nano-te...
