Paper Abstract

Singlet and triplet states of negatively (X-) and positively (X+) charged excitons (trions) in ZnSe-based quantum wells have been studied by means of photoluminescence in pulsed magnetic fields to 50 Tesla. Singlet state binding energies of X- show a monotonic increase with growing magnetic fields with a tendency to saturation. Contrary to that a decrease of X+ binding energy is found. A crossover of the triplet and singlet states is observed in magnetic fields 35 - 50 T.
