目的 通过激光后处理技术在二维周期性结构表面实现对结构色色调的调控,并通过添加波导层的方式提高结构色的饱和度。方法 实验中通过气-液界面自组装的方法制备二维光子晶体结构色基底,并在其表面沉积一层金膜,随后使用激光后处理的方式对样品进行扫描处理,并添加波导层结构实现高饱和度结构色调控。结果 表面镀膜后的二维胶体晶体基底颜色随着测量角度的增加逐渐红移,呈现出蓝色—蓝绿色—橙色—橘红色的色调变化,使用激光后处理的方式扫描基底后,随着扫描速度的增加,样品的衍射光谱向长波方向有一定程度的移动,添加波导层结构后呈现出较高的饱和度,实现了淡蓝色—青蓝紫色—蓝绿色—橘黄色—红色的颜色转变。结论 通过激光处理和添加波导层的方法可实现对二维光子晶体结构色的基底颜色色调及饱和度的调控,在光学防伪、印刷包装等领域具有巨大的应用前景。
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.
