Abstract
The invention belongs to the technical field of nano-silver preparation, and discloses a preparation method of a kelp-shaped nano-silver structure. The preparation method comprises the following stepsthat S1, a mixed solution of hydrofluoric acid, silver nitrate and SDS is prepared; S2, a cleaned silicon wafer is soaked in the mixed solution prepared in the S1 to react for a period of time; and S3, after the reaction, the silicon wafer is cleaned up, and blow-drying is carried out to obtain the kelp-shaped nano-silver structure, wherein in the S1, the concentration of the hydrofluoric acid inthe mixed solution is 10<-6> M-10 M, the concentration of the silver nitrate in the mixed solution is 10<-6> M-1 M, and the concentration of the SDS in the mixed solution is 10<-6> M-1 M. The methodis simple to operate, low in cost and simple and convenient in process, and facilitates the preparation of a novel kelp-shaped nano-silver structure.
Description
technical field [0001] The invention belongs to the technical field of nano-silver preparation, and more specifically relates to a preparation method of a kelp-shaped silver structure. Background technique [0002] Silver micro-nanostructures are strongly coupled with visible light through resonance excitation, that is, surface plasmon resonance. Based on surface plasmon resonance, silver micro-nanostructures can be widely used in catalysis, energy, sensing and other fields. It has been demonstrated that the surface plasmon resonance strongly depends on the size and morphology of silver micro-nanostructures. [0003] At present, the common silver structure shapes include flake, line, sphere, triangle, cube, octahedron and so on. There is no kelp-shaped silver micro-nano structure in the prior art. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, and to provide a preparation met...
