【講座信息】

納米等離子體激元可以定義為使用尺寸遠小於輻射波長的材料研究光的操縱的一種科學。該技術可廣泛用於傳感和診斷等各種領域。納米彈性體的一個重要組成部分是納米結構材料，通常是由貴金屬製成的🛍，由於它們能夠支持自由（傳導）電子的相幹振蕩📙，因此可以非常有效地吸收和散射光。眾所周知，150多年前“精細分裂”金屬被研究發現其具有顯著光學響應🟠👉🏿，但最近開發的復雜表征技術和建模方法已經大大重新激發了該領域的研究熱點🙏🏿。其中一個最重要的發展就是納米等離子體製造方法的創新研究，這使我們能夠精確控製納米結構金屬的成分和形態🦹🏿。膠體化學法特別具有簡單和大規模生產的優點，同時可以改變其中的參數來引導納米顆粒形態，以及引導表面性質和後續加工過程⚔️。

本次報告將基於一系列的納米等離子體製造方法，這些方法可以微調納米等離子體構建塊的形態，最終目標是改善其光學特性及其在傳感應用中的性能。本次報告稿還會列舉幾個關於改進的合成和受控自組裝成納米結構材料的實例𓀘，其主要測納米結構是金納米顆粒🖇。

Nanoplasmonics can be defined as the science studying the manipulation of light using materials of size much smaller than the radiation wavelength. This technology finds applications in various fields including sensing and diagnostics. An essential component of nanoplasmonics are the nanostructured materials, typically noble metals, which can very efficiently absorb and scatter light because of their ability to support coherent oscillations of free (conduction) electrons. Although the remarkable optical response of “finely divided” metals is well known since more than 150 years ago, the recent development of sophisticated characterization techniques and modeling methods has dramatically reactivated the field. An extremely important pillar on which the development of nanoplasmonics has been based comprises the impressive advancement in fabrication methods, which provide us with an exquisite control over the composition and morphology of nanostructured metals. Colloid chemistry methods in particular have the advantage of simplicity and large scale production, while offering a number of parameters that can be used as a handle to direct not only nanoparticle morphology but also surface properties and subsequent processing.

This talk will be based on a selection of fabrication methods that allow fine tuning of the morphology of nanoplasmonic building blocks, with the ultimate goal of improving their optical properties and their performance in sensing applications. Several examples will be presented regarding improved synthesis and controlled self-assembly into nanostructured materials, focusing mainly on gold nanoparticles.
