Abstract

A method for preparing a metal structure on the surface of a transparent material by using a metal nanoparticle ink, comprising: placing a transparent substrate (6) in a metal nanoparticle ink (8), using a laser (1) to irradiate the substrate, selectively depositing the metal material in the metal nanoparticle ink at the laser focusing point on the surface of the substrate by controlling parameters of the laser and the material and the concentration of the ink, and finally forming a metal micro-nano structure on the surface of the transparent substrate. The preparation method is directly performed in a liquid phase, the laser can directly reach the surface of a transparent substrate, and metal particles in a metal nanoparticle ink are sintered into a stable conductive metal layer, simplifying the preparation process. The metal oxidation rate is low during the preparation process, and a metal layer having a controllable size is only selectively formed at the laser focusing point, preventing the deposition of metal particles on the whole surface of the substrate, saving raw materials, reducing energy consumption and production costs.

Description

technical field [0001] The invention belongs to the field of laser processing, and relates to a laser printing method, in particular to a method of using metal nano-ink to carry out laser printing on the surface of a transparent material. Background technique [0002] At present, devices based on transparent materials have been widely used in the technical fields of optics, consumer electronics, biomedicine and micro-opto-electro-mechanical systems. The preparation of metal structures on the surface of transparent materials is a relatively common modification method, and the methods used mainly include: (1) conventional deposition method and (2) laser deposition preparation method. In the preparation of surface micro-nano structures of transparent materials, laser direct writing has unique advantages, such as no need for vacuum, which can reduce costs and simplify the processing process. [0003] At present, the methods of direct and indirect laser solid-phase preparation m...
