N2 - We investigate the homogeneous linewidth of localized type-I excitons in type-II GaAs/AlAs superlattices. These localizing centers represent the intermediate case between quasi-two-dimensional and quasi-zero-dimensional confinements. The temperature dependence of the homogeneous linewidth is gained with high precision from micro-photoluminescence spectra. We confirm the reduced exciton-acoustic-phonon interaction with decreasing dimensionality. An enhancement of the average exciton-LO-phonon interaction by localization is found in our sample. But this interaction is very sensitive to the detailed structure of the localizing centers.
