Unprecedented in situ formation of artificial moth-eye structure is demonstrated by spontaneous nano-phase separation of a silica-based system on substrate. The moth-eye thin film with a homogenously distributed nipples array shows broadband antireflection functionalities. The mechanism of nano-phase separation is unveiled as spinodal decomposition by chemical freezing method and thermodynamic analysis. The current method may provide a new avenue to ready fabrication of patterned nanostructures toward a variety of applications.
通过在基底上的基于二氧化硅的体系的自发纳米相分离，展示了前所未有的人工蛾眼结构的就地形成。具有均匀分布的乳突阵列的蛾眼薄膜表现出宽带抗反射功能。通过化学冷冻法和热力学分析揭示了纳米相分离的机制是旋节分解。该方法可能为各种应用的图案化纳米结构的制备提供新途径。
