Advanced functional luminescence
Dr Nathaniel Davis
Gaps exist in the research field where physics blends into chemistry. In the Advanced Functional Luminescence group, we take a chemical stance to solve challenges related to the advancement of solar energy, energy conversion and efficient lighting. Our focus is on the creation of materials allowing light and electronic energy to be interchanged.
Photo-active antenna complexes have existed for the last decade or so, but they are not presently widely used in applications. Our goal is to link organic and inorganic chromophores together to create energy-harvesting systems with spectral management techniques that are more efficient and applicable compared to the previous generation chromophores. Once fabricated these structures have the potential to advance a wide range of optoelectronic applications. These large antenna complexes will mimic the efficient light harvesting complexes found in nature, concentrating, splitting or combining excited states, and have potential applications in photovoltaics (PVs), luminescent solar concentrators (LSCs), down converters, light emitting diodes (LEDs), water splitting and optically and electronically pumped lasers. They will also act as compelling models to observe excited state dynamics using laser spectroscopy, which has the potential to provide fundamental knowledge that feeds back into future applications.
