Efficient dipole-dipole coupling of Mott-Wannier and Frenkel excitons in (Ga,In)N quantum well/polyfluorene semiconductor heterostructures
Itskos, Grigorios; Heliotis, G.; Lagoudakis, P. G.; Lupton, J.; Barradas, N. P.; Alves, E.; Pereira, S.; Watson, I. M.; Dawson, M. D.; Feldmann, J.; Murray, R.; Bradley, D. D. C. (2007)We investigate interactions between Mott-Wannier (MW) and Frenkel excitons in a family of hybrid structures consisting of thin organic (polyfluorene) films placed in close proximity (systematically adjusted by GaN cap layer ...

Efficient förster transfer mediated by excitons in InGaN/GaN quantum well/polyfluorene heterostructures
Itskos, Grigorios; Heliotis, G.; Belton, C.; Watson, I. M.; Dawson, M. D.; Bradley, D. D. C.; Murray, R. (2007)We report on novel InGaN/GaN quantum well/polyfluorene heterostructures where efficient Förster energy transfer from the well to the organic layer occurs. We show that Mott-Wannier excitons dominate the quantum well ...

Hybrid inorganic/organic semiconductor heterostructures with efficient non-radiative energy transfer
Heliotis, G.; Itskos, Grigorios; Murray, R.; Dawson, M. D.; Watson, I. M.; Bradley, D. D. C. (2006)A hybrid inorganic/organic semiconductor structure employing a polyfluorene thin films with Efficient non-radiative Förster resonant energy transfer (FRET) was fabricated. FRET is mediated by dipole-dipole interactions, ...

Low-threshold lasers based on a high-mobility semiconducting polymer
Heliotis, G.; Choulis, Stelios A.; Itskos, Grigorios; Xia, R.; Murray, R.; Stavrinou, P. N.; Bradley, D. D. C. (2006)Progress toward electrically driven conjugated polymer lasers should benefit from the identification of materials that exhibit good charge transport properties coupled with large optical gain. Here, we report a detailed ...
