【讲座信息】

智能材料对所施加的外部刺激表现出化学和物理反应，具有广阔的应用前景。 本演讲将重点介绍具有响应光学特性的纳米结构材料的合成和制造，该材料可用于印刷，传感，标识，安全文件，显示器和能量转换等领域。 我们将讨论最近在开发具有多种功能的混合纳米结构的化学合成方面取得的进展，以及将其组装成二级纳米结构的新方法，其可通过控制纳米级构建块的空间排列和取向来主动调整其光学性质。 通过操纵光和纳米结构之间的相互作用，例如衍射，折射，双折射和电子共振，已经开发出许多具有可见光和红外输出的新型光学材料。

 Smart materials hold great promises for many intrigue applications as they exhibit chemical and physical responses to the applied external stimuli. This presentation will focus on the synthesis and fabrication of nanostructured materials with responsive optical properties that can find applications in printing, sensing, signage, security documents, displays, and energy conversion. We will discuss our recent advances on the development of rational chemical synthesis of hybrid nanostructures with multiple functionalities and the novel approaches to assembling them into secondary nanostructures whose optical properties can be actively tuned by controlling the spatial arrangement and orientation of the nanoscale building blocks. Many novel optical materials with visible and infrared outputs have been developed by manipulating the interaction between light and the nanostructures, such as diffraction, refraction, birefringence, and electronic resonances.
