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”，以了解和增长的非线性形状，以实现所需的光学特性。金属晶体的小平面仅由几个原子组成，这些原子对其生长和性能至关重要。该项目旨在开发测量这些原子的位置和稳定性的方法，以了解控制它们组装的因素，并了解它们对纳米粒子性质的影响。它计划以前所未有的空间和能量分辨率将原子结构和相应的光激发关联起来。结合这些进展，该项目旨在将纳米面化学，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。
