摘要
基于Fabry-Pérot(F-P)纳米腔创建的结构色,在高分辨率显示、高密度光学数据存储和防伪等领域有巨大的应用潜力。本研究针对包含不同底层金属材料和中间介质材料的四种非对称F-P纳米腔结构,保持纳米腔尺寸恒定,通过改变周期性纳米腔阵列的填充密度调控结构色的颜色属性,使用时域有限差分法(FDTD)分析探究了填充密度对色相和饱和度的影响。实验结果发现,通过改变填充密度可以有效实现对生成结构色的色相和饱和度的调控,提供了以固定的腔厚度扩展干涉结构色色域的自由度。本研究对使用非对称F-P纳米腔实现广色域、高饱和度和高分辨率的结构色有指导性意义。
Structural color based on Fabry−Pérot(F-P)nanocavities has great application potential in high-resolution display,high-density optical data storage and anti-counterfeiting.In this study,the lateral dimensions of four asymmetric F-P nanocavities containing different underlying metal materials and intermediate dielectric materials were maintained constant,and the color properties of structural color were adjusted by only changing the fill density of periodic nanoarrays.The influence of fill density on the hue and saturation of structural color was analyzed and explored by the method of Finite Difference Time Domain(FDTD).The results showed that when keeping the dimension constant and only changing the fill density,the hue and saturation of the generated color can be effectively controlled,which provides a degree of freedom to extend the color gamut of the interferometric structure with a fixed cavity thickness.It is of guiding significance for the use of asymmetric F-P nanocavities to achieve wide color gamut,high saturation and high resolution of structural color.
