Abstract

We investigate the lineshape of the zero-phonon luminescence of the A-exciton polariton and of the LO-phonon replicas in ZnO and their dynamics. The lineshape verifies details of the A-exciton polariton model and confirms the inverted band structure (AΓ7, BΓ9, CΓ7). The dynamics give information on relaxation, diffusion and recombination processes. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
