Abstract

The invention discloses a preparation method of a flexible photoelectric substrate doped with sea urchin-shaped gold nanoparticles, and belongs to the field of photoelectric device preparation. The doped flexible substrate provided by the present invention adopts ultraviolet light curing material as the substrate, sea urchin-shaped gold nanoparticles with different surface shapes and sizes as the dopant, and the substrate is covered with flexible transparent electrodes. Among them, sea urchin-shaped gold nanoparticles are prepared by a solution method using chloroauric acid as a soluble gold source, using different reducing agents and reaction conditions. Compared with the existing technology, the present invention adopts the Meyer rod roll coating method to prepare transparent silver nanowire electrodes, disperses sea urchin-like gold nanoparticles in the substrate precursor solution, and uses ultraviolet curing technology to cure the substrate precursor solution, and The silver nanowires are transferred to the substrate to be used in the preparation of optoelectronic devices. By changing the surface morphology and size of the sea urchin-shaped gold nanoparticles in the substrate precursor solution, the optical field enhancement effect and enhanced spectrum of the flexible substrate can be adjusted.

Description
