ARC CENTRE OF EXCELLENCE IN EXCITON SCIENCE (UOM CONTRIBUTION)
Grant number: CE170100026 | Funding period: 2017 - 2023
This Centre aims to manipulate the way light energy is absorbed, transported and transformed in advanced molecular materials. The research programme spans high-throughput computational screening, single molecule photochemistry and ultrafast spectroscopy and embraces innovative outreach and commercial translation activities. The Centre plans to capture the knowledge generated as new intellectual property, materials processing know-how, and through the creation of new employment opportunities. The expected outcomes and benefits include new Australian technologies in solar energy conversion, energy-efficient lighting and displays, security labelling and optical sensor platforms for defence.
