Abstract

The invention provides a femtosecond laser-based transparent conductive oxide polarizing and detecting realization method, which belongs to the field of functional materials. The transparent conductive oxide is plated on the surface of an optical device in need of polarizing and detecting functions, the photoelectric device plated with the transparent conductive oxide is placed in a femtosecond laser microprocessing system, the energy and the scanning speed of specific femtosecond laser are adjusted, and a large-area and uniform transparent conductive oxide grating structure is prepared on thesurface of the photoelectric device. The prepared grating structure can block polarized light perpendicular to the structure direction, thereby reducing the transmissivity of the polarized light perpendicular to the processing direction. Compared with the prior art, the method provided in the invention is simple and easy to realize, the processed grating has stable structural properties, the manufactured product can turn circular polarized light to linear polarized light, and an important application value is realized in aspects of polarizing and detecting of the photoelectric device.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a method for realizing polarization and analysis of transparent conductive oxides based on a femtosecond laser. Background technique [0002] In optoelectronic devices, in order to obtain a single polarization or filter out light in other polarization directions, polarizers are used. One method of formulating the polarizer is to use a polyvinyl alcohol polymer compound film with a network structure as the film base, immerse it in iodine solution, and then stabilize it after being reduced by boric acid aqueous solution, and then stretch it 4-5 times directional. , so that the macromolecules are oriented. That is, after stretching, the polymer material changes from a network structure to a linear structure, and iodine molecules are neatly adsorbed on the film to have polarizing or polarizing properties. This preparation method is weak and unstable. In addition, the...
