Excited-state engineering of novel optical material platforms for application in quantum technologies.
We explore novel material systems, ranging from defects in two-dimensional materials to molecular semiconductors, for quantum light emission, quantum memory and solar energy harvesting applications. In particular, we investigate the the excited-state dynamics and spin physics of localised excitations in these materials. Our goal is to utilise our findings to ultimately engineer excited states, and use this understanding to build new devices for next generation technologies.
