| 摘 要： | 对彩色吉丁虫Chrysochroa raja、节日虎甲虫Chrysina chrysagyrea等甲虫体壁多层薄膜结构色的机理进行了理论分析。当薄膜各层光学厚度近似等于可见光波长(380～750 nm)的四分之一时,分析了各膜层厚度、折射率以及入射角对单层薄膜和多层薄膜的反射率影响。计算结果表明甲虫彩虹色由多层膜薄膜的反射干涉而成,其反射谱带宽随着的增大而增大,高低折射率薄膜的光学厚度各自变化但总和保持不变时,薄膜颜色无明显变化,入射角对单层薄膜和多层薄膜的反射率都有一定的影响。这些结论将为进一步认识和研究甲虫的颜色和制备新一代仿生薄膜材料提供理论指导。

| Abstract: | Physical mechanism of structural colors of multi-layer thin film of beetles(such as Chrysochroa raja,Cicindela scutellaris,Chrysina chrysagyrea et.al.) was theoretically studied.We established ideal models of single-layer and multilayer thin films by optical principle,and analyzed the reflective properties of the ideal model.Moreover,the results can provide theoretical support for further understanding and studying structural colors of beetle's thin-film structure and preparing novel biomimetic materials. |
