【讲座信息】

纳米等离子体激元可以定义为使用尺寸远小于辐射波长的材料研究光的操纵的一种科学。该技术可广泛用于传感和诊断等各种领域。纳米弹性体的一个重要组成部分是纳米结构材料，通常是由贵金属制成的，由于它们能够支持自由（传导）电子的相干振荡，因此可以非常有效地吸收和散射光。众所周知，150多年前“精细分裂”金属被研究发现其具有显着光学响应，但最近开发的复杂表征技术和建模方法已经大大重新激发了该领域的研究热点。其中一个最重要的发展就是纳米等离子体制造方法的创新研究，这使我们能够精确控制纳米结构金属的成分和形态。胶体化学法特别具有简单和大规模生产的优点，同时可以改变其中的参数来引导纳米颗粒形态，以及引导表面性质和后续加工过程。

本次报告将基于一系列的纳米等离子体制造方法，这些方法可以微调纳米等离子体构建块的形态，最终目标是改善其光学特性及其在传感应用中的性能。本次报告稿还会列举几个关于改进的合成和受控自组装成纳米结构材料的实例，其主要测纳米结构是金纳米颗粒。

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.
