Start year: 2005

Summary: Cathodoluminescence (CL), the emission of light during electron irradiation, has emerged as a unique analytical tool to characterise luminescence centres and study luminescence mechanisms in technologically important materials at the nano-scale. The main aim of this project is to establish a state-of-the-art scanning CL microscopy and spectroscopy facility in Australia. The facility will enable high spatial resolution CL analysis of technologically important semiconductors and novel nano-structured materials, e.g. quantum dots and ceramic nano-crystals. These studies will facilitate a deeper understanding of the physics of light emission from nano-structured materials and enable the fabrication of higher quality opto-electronic materials.
