Long-range exciton transport in conjugated polymer nanofibers prepared by seeded growth.
in Science (New York, N.Y.)
| Description | Novel micellar structures synthesised at the University of Bristol have been studied in Cambridge. These contain well-organised short semiconductor polymer chains that form structures of several hundred nanometers. Our measurements of time-resolved luminescence reveal that photoexcitations are able to diffuse up to 200 nm - an exceptionally large range for any molecular semiconductor. These results were published in Science (2018). |
| Exploitation Route | These structures are potentially useful as light-harvesting elements in novel photodetectors |

| Description | This project resulted in a significant paper (Science, 2018) in which we report nano-platelet semiconductor structures that show important optoelectronic properties. Specifically, the energy from absorbed light (in the form of 'molecular excitons) can move a significant distance within these structures, and this is very attractive for light-harvesting applications in photodetectors or solar cells. |
