This project aims to provide a ‘toolkit’ to understand and grow nanocrystal shapes to achieve desired optical properties. The facets of a metal nanocrystal comprise just a few atoms, which are pivotal to its growth and properties. This project aims to develop methods to measure the location and stability of these atoms to understand the factors controlling their assembly and to understand their impact on the properties of the nanocrystal. It plans to correlate atomic structure and corresponding optical excitations with unprecedented spatial and energy resolution. Combining these advances, the project aims to relate nanofacet chemistry, structure, stability and optical excitations to deliver a new understanding of optical properties and their control.

该项目旨在提供一个“工具包”来理解和生长纳米晶体形状，以实现所需的光学特性。金属纳米晶体的面仅包含几个原子，这对其生长和特性至关重要。这些原子的位置和稳定性，以了解控制其组装的因素，并了解它们对纳米晶体特性的影响。它计划将原子结构和相应的光学激发与前所未有的空间和能量分辨率结合起来。该项目旨在将纳米面的化学、结构、稳定性和光学激发联系起来，以提供对光学特性及其控制的新理解。
