Abstract

The invention relates to a method for preparing a magnetic photonic crystal on the basis of biological templates of single scales of a butterfly wing. The method comprises the steps of: carrying surface pretreatment on a whole butterfly biological template; preparing a precursor metal-sol gel solution; placing the treated biological template in the prepared precursor solution for soaking treatment; after the soaking, taking out a sample, flushing by distilled water and drying; under the help of a microscope, selecting soaked single scales and drying by using a drying oven; roasting to remove the biological templates of the single scales to obtain a single butterfly scale ferric oxide material keeping a photonic crystal structure; and further sintering and reducing under hydrogen-argon mixed gas to obtain a single butterfly scale magnetic ferroferric oxide material keeping the photonic crystal structure. The prepared single butterfly scale magnetic material with the natural photonic crystal structure has good response to magnetism and light, can be controlled within a scale range from nanometer to micrometer and has a potential application prospect in the field of magneto-optical communication devices.

Description

Technical field [0001] The invention belongs to the field of materials science, and in particular relates to a method for preparing magnetic photonic crystals based on a single butterfly wing scale biological template. Specifically, it relates to a single butterfly scale using a secondary sintering method to prepare a single material. Flake magnetic photonic crystal method. Background technique [0002] Since the concept of photonic crystal was put forward, it has attracted widespread attention. Because of its special properties that can regulate light, it has potential applications in communications, optical transmission, and nanodevices. [0003] The preparation of photonic crystals that can regulate light in the visible light range is still a very expensive and challenging task under the current experimental technical conditions. The difficulty lies in the preparation of periodic, tens of nanometer to micrometer size structures. And this kind of structure exists widely in natu...
