The properties of nano-scale materials can differ significantly from those of their bulk counterparts. As such, they can provide materials with new and novel properties as well as proving a useful test of modern theories. An outstanding example of the significance of such effects is provided by quantum confined silicon structures, such as porous or nanocrystalline silicon, which exhibit luminescence efficiencies up to a million times greater than bulk silicon. This project aims to understand the novel optical properties and interactions that underpin potential applications of this technologically important material.

纳米级材料的性质与它们的块状材料有很大的不同。因此，它们可以提供具有新颖特性的材料，并为现代理论提供有用的检验。量子限制硅结构（如多孔硅或纳米晶硅）提供了这种效应重要性的一个突出例子，它们的发光效率比体硅高100万倍。该项目旨在了解支撑这种技术重要材料潜在应用的新型光学特性和相互作用。
