构建三维（3D）等离子体纳米结构的直接组装方法通过二维金属纳米孔薄膜的应变诱导自卷起产生多孔等离子体卷。该路线可扩展到不同的孔尺寸和薄膜厚度，并适用于各种材料，为具有纳米工程光学特性的各种 3D 超材料系列提供通用路线。这些等离激元卷可以通过光照射动态驱动，随着光强度的增加或减少而滚动或展开。这种动态可控的 3D 等离子体纳米结构为有源纳米执行器中的传感和反馈提供了机会。 (C) 2012 年美国物理研究所。 [http://dx.doi.org/10.1063/1.4711923]
A direct-assembly method to construct three-dimensional (3D) plasmonic nanostructures yields porous plasmonic rolls through the strain-induced self-rolling up of two-dimensional metallic nanopore films. This route is scalable to different hole sizes and film thicknesses, and applicable to a variety of materials, providing general routes towards a diverse family of 3D metamaterials with nano-engineerable optical properties. These plasmonic rolls can be dynamically driven by light irradiation, rolling or unrolling with increasing or decreasing light intensity. Such dynamically controllable 3D plasmonic nanostructures offer opportunities both for sensing and feedback in active nano-actuators. (C) 2012 American Institute of Physics.
