摘要
通过变角度光谱系统测量了绿带翠凤蝶闪亮后翅中微纳结构的光谱,并建立了多层膜反射结构模型来解释蝴蝶翅膀的结构色产生机理。通过测量绿带翠凤蝶后翅微结构中的圆二向色性光谱,研究了其光学偏振特性。基于结构色的特点,设计并实现了利用蝴蝶翅膀对溶液折射率的传感实验,结果表明随着折射率的增大,反射光谱谱线发生红移。相关的研究结果为理解自然界中微结构材料的偏振和传感应用提供了基础。
The optical property of the flashing hind wings of the Papilio maackii were measured by an angle resolved spectrum system. A multilayer reflection structure model was established to explain the mechanism of the structural color of the butterfly wings. The circular dichroism in the microstructure of the hind wings of the butterflies was measured and the polarization properties were verified. Based on the structural color, the sensing experiments of the refractive index of solutions by using butterfly wings were designed and implemented. The results show that the spectra of butterfly wings redshift with the increase of the refractive index of solutions. The research provides a technological platform for polarization and sensing applications based on the microstructures in nature.
