Abstract

The work aims to control the hue of structural colors on the two-dimensional periodic structure through laser post-processing technology, and increase the saturation of structural colors by adding waveguide layers. A two-dimensional photonic crystal substrate was prepared by self-assembly at the gas-liquid interface, and a layer of gold film was deposited on its surface. Then, the sample was processed by laser post-processing technology, and a waveguide layer was also added to obtain high saturation structural color effect. As a result, after coating, the color of the two-dimensional colloidal crystal substrate gradually shifted red with the increase of detecting angle, showing a color hue change of blue - blue-green - orange - orange red. After post-processing of the substrate by laser, the diffraction spectrum of the sample shifted to the long wave direction with the increase of scanning speed. Subsequently, it showed a high saturation and achieved a color transition from light blue - cyan purple - blue-green - orange yellow - red after addition of waveguide layer. The method of laser post-processing and addition of waveguide layers can control the color hue and saturation of two-dimensional photonic crystal precisely, which has great application prospects in the fields of optical anti-counterfeiting, printing and packaging.
