【講座信息】

智能材料對所施加的外部刺激表現出化學和物理反應，具有廣闊的應用前景。 本演講將重點介紹具有響應光學特性的納米結構材料的合成和制造，該材料可用于印刷，傳感，標識，安全文件，顯示器和能量轉換等領域。 我們將討論最近在開發具有多種功能的混合納米結構的化學合成方面取得的進展，以及將其組裝成二級納米結構的新方法，其可通過控制納米級構建塊的空間排列和取向來主動調整其光學性質。 通過操縱光和納米結構之間的相互作用，例如衍射，折射，雙折射和電子共振，已經開發出許多具有可見光和紅外輸出的新型光學材料。

 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.
