We develop reflective color filters with randomly distributed nanodisks and nanoholes fabricated with hydrogen silsesquioxane and Ag films on silicon substrate. They exhibit high resolution, angle-independence and easily up-scalable fabrication, which are the most important factors for color filters for industrial applications. We uncover the underlying mechanism after systematically analyzing the localized surface plasmon polariton coupling in the electric-field distribution. The agreement of the experimental results with those from the simulation indicates that tunable colors across the visible spectrum can be obtained by simply varying the diameter of the nanodisks, promoting their applications.
我们使用氢化硅倍半氧烷和银薄膜在硅衬底上制作了具有随机分布纳米盘和纳米孔的反射式彩色滤光片。它们具有高分辨率、角度无关性和易于扩展的制造工艺，这些都是工业应用彩色滤光片的最重要因素。我们通过系统地分析电场分布中的局域表面等离子体激元耦合，揭示了其背后的机制。实验结果与模拟结果的一致性表明，通过简单地改变纳米盘的直径，可以获得整个可见光谱范围内的可调颜色，从而促进了它们的应用。
