在这项工作中，一个新的混合光学Janus颜色架构的介绍，可以导致令人印象深刻的，高度定向的光学特性。基于简单而直接的退火过程，产生薄的金属纳米颗粒超颖表面，其形成强的光吸收层并在多层结构中产生光学Janus效应。在结构着色材料的一侧上观察到的反射颜色与在另一侧上获得的反射颜色显著不同。在不同的几何和组成情况下的系统的光学性质进行。非对称彩色材料在显示器、彩色滤光片、建筑、防伪标签等方面具有广阔的应用前景。
In this work, a new hybrid optical Janus color architecture is introduced that can lead to impressive, highly directional optical properties. Based on a simple and straightforward annealing process, a thin metallic nanoparticle metasurface is produced, which forms a strong light absorption layer and creates optical Janus effects in a multilayer structure. The observed reflective color is remarkably different on one side of the structurally colored material than that obtained on the other side. The optical properties of the systems under different geometric and compositional situations are performed. The asymmetric color materials could hold broad application prospects such as displays, color filters, architecture, and anti-counterfeit labels.
