Excitons in vertically stacked type-II quantum dots (QDs) experience a topological magnetic phase and demonstrate Aharonov-Bohm oscillations in emission intensity. The photoluminescence of vertically stacked ZnTe∕ZnSe QDs is measured in magnetic fields up to 310.3em0exT. Aharonov-Bohm oscillations are found in the magnetic-field dependence of the emission intensity. The positions of the peaks of the emission intensity are in good agreement with numerical simulations of excitons in stacked QDs.
