Abstract:

Smart materials offer exciting possibilities for broad applications due to their ability to respond chemically or physically to external stimuli. This presentation highlights our efforts in developing magnetic assembly approaches to producing smart optical materials applicable in printing, sensing, signage, security documents, and displays. We will begin by reviewing our initial successes in synthesizing magnetic nanostructures and assembling them into periodic structures that respond dynamically to external magnetic fields. By modulating the interaction between light and these nanostructured assemblies, we demonstrate the potential for developing innovative optical materials through control of diffraction, refraction, birefringence, plasmonic resonances, and chiroptical properties. Specifically, we will share our recent progress on creating magnetic/plasmonic hybrid nanostructures and assembling them into smart materials with tunable optical and mechanical features, achieved by manipulating the spatial arrangement and orientation of these nanoscale components using magnetic approaches.

报告摘要：

智能材料因能够对外部刺激产生化学或物理响应，在广泛应用中展现出令人期待的前景。本报告将介绍我们在发展磁性组装方法制备智能光学材料方面的研究工作，这类材料可应用于印刷、传感、标识、防伪文件和显示等领域。报告首先回顾我们在合成磁性纳米结构并将其组装成可对外磁场作出动态响应的周期性结构方面取得的初步成果。通过调控光与这些纳米结构组装体之间的相互作用，我们展示了通过控制衍射、折射、双折射、等离激元共振和手性光学性质来发展新型光学材料的潜力。具体而言，我们将分享近期在构筑磁性/等离激元杂化纳米结构，并将其组装成具有可调光学和力学特性的智能材料方面的进展；这些特性是通过磁性方法调控纳米尺度组分的空间排列和取向而实现的。
