A brand-new approach to realizing visible-infrared compatible camouflage is proposed based on a metal-based graphical hetero-structure (MGHS) SiO₂/Ag/ZnS/Ag. For different thicknesses (20, 40, and 60 nm) of color-controlling sub-layer, high-contract and large-span structure colors (yellow, navy, and cyan) were observed due to reintroducing constructive interference with a matching intensity of reflected waves. Ultra-low infrared emissivity values of 0.04, 0.05, and 0.04 (with high average reflectance values of 95.46%, 95.31%, and 95.09%) were obtained at 3⁻14 μm. In addition, the well-performing trisecting-circle structure further indicates that it is feasible to design on-demand compatible camouflage patterns using the easily-prepared MGHS.
基于金属基图形异质结构(MGHS)SiO₂/Ag/ZnS/Ag,提出了一种实现可见-红外兼容伪装的全新方法。对于不同厚度(20、40和60纳米)的颜色控制子层,由于重新引入了具有匹配反射波强度的相长干涉,观察到了高对比度和大跨度的结构颜色(黄色、藏青色和青色)。在3至14微米处获得了0.04、0.05和0.04的超低红外发射率值(平均高反射率值分别为95.46%、95.31%和95.09%)。此外,性能良好的三等分圆结构进一步表明,使用易于制备的MGHS设计按需兼容伪装图案是可行的。
