The desire to reproduce vivid colors such as those found in birds, fishes, flowers, and insects has driven extensive research into nanostructured surfaces especially because of their high spatial resolution. Using a periodic silicon-patterned structure coated with aluminum, we combine two distinct and yet interconnected effects to produce bright and vivid color surfaces. A genetic algorithm optimization process was used to fine-tune both the diffraction and plasmonic effects to obtain reflective color filters for the red, green, and blue colors. The obtained structures are suitable for displays, image applications, color sensors, and optical filters.

明亮而生动的衍射–等离子体反射滤光片,用于产生颜色

再现鲜艳色彩(例如在鸟类,鱼类,花朵和昆虫中发现的色彩)的愿望推动了对纳米结构表面的广泛研究,尤其是由于它们具有很高的空间分辨率。通过使用涂有铝的周期性硅图案结构,我们结合了两种截然不同但又相互关联的效果,以产生明亮鲜艳的色彩表面。遗传算法优化过程用于微调衍射和等离子体效应,以获得用于红色,绿色和蓝色的反射式彩色滤光片。所获得的结构适用于显示器,图像应用,颜色传感器和滤光器。
