Method for constructing silver film trap structure on metal surface using ps microspheres as template

A silver film trap, metal surface technology, applied in the process, microstructure technology, microstructure device and other directions for producing decorative surface effects, can solve the problem that the size and distribution uniformity of nanopore arrays cannot be well controlled, and cannot be very well controlled. It is easy to control the size of the nanopore array structure and the uncontrollable etching process, so as to achieve the effect of easy mass production, lower secondary electron emission coefficient and strong repeatability.

Problems solved by technology

However, electrochemical corrosion is often carried out along the grain boundary surface of the corroded material, and the general metal material itself is anisotropic, so the nanopore array structure etched by this method will also show anisotropy. The size and distribution uniformity of the formed nanohole array structure cannot be well controlled
[0005] Through operations such as ultrasonic cleaning, spin coating, baking, exposure, baking, development treatment, and etchant etching in sequence, the construction of a regular nanohole array structure on the surface of microwave components can also be realized, but this method uses patterned light Resist is used as a template to selectively etch microwave components. There are many operating procedures, and the etching process is also uncontrollable, and the size of the formed nanohole array structure cannot be well controlled.

Abstract

The invention relates to a method for constructing a silver film trap structure on a metal surface by utilizing PS microspheres as a template. In a conventional process for preparing a metal nano-porous array, the equipment requirement is strict, the cost is high, or the template morphology needs to be subjected to earlier-stage development, and time consumption is high. The method comprises the following steps: self-assembling PS microspheres on the metal surface through an evaporation deposition method; with the PS microspheres as the template, plating silver in gaps between the PS microspheres by utilizing an electrochemical deposition method, and finally, removing the PS microsphere template by using an organic solvent, and constructing the silver film trap structure on the metal surface. The method is high in operability, the constructed silver film trap structure is high in crystalline quality, and impurity residues are avoided. Meanwhile, the process for self-assembling the PS microspheres on the metal surface is simple, the repeatability is high, and the secondary electron emission coefficient on the metal surface can be reduced to be over 25 percent.

technical field [0001] The invention relates to a method for constructing a silver film trap structure on a metal surface, in particular to a method for constructing a silver film trap structure on a metal surface by using PS microspheres as a template. Background technique [0002] The trap structure of the silver film, in layman's terms, is the nanoscale porous structure constructed on the surface of the metallic silver film, that is, the so-called nanopore array structure. Using the metal nanohole array structure can effectively excite and adjust the metal surface plasmon resonance (SPR) phenomenon, thereby stimulating some special optical effects, such as the ultra-strong optical transmission effect (EOT), the surface Raman enhanced effect (SERS), the surface The enhanced fluorescence effect (SEFS) can be used in biochemical detection sensors, nano-optical devices, and solar cells.
