Abstract
We report on microphotoluminescence experiments in magnetic fields on single quantum dots formed by width fluctuations in a narrow GaAs/AlxG a1-xAs quantum well. The ground state as well as two excited states ar e discussed. We find a different diamagnetic shift and Zeeman spin spl itting for these states. Resonantly exciting zero-dimensional excitons , we observe a strong magnetic-field dependence of the spin flip rates .
