BastardWe report the observation of a blue shift of very sharp luminescence lines in GaAs/AlGaAs quantum wires at increasing excitation density. These sharp lines correspond to recombination of one-dimensional excitons localized in local potential minima due to interface disorder. The evolution of the fine-structured photoluminescence spectra with increasing exciton density is interpreted in terms of many-body effects which lead to an increase of the exciton self-energy and to the formation of excitonic complexesA. semiconductorsA. nanostructuresD. optical propertiesD. exchange and superexchange
