Negatively charged excitons (trions) were observed in unintentionally donor doped Zn0.90Mg0.10Se/ZnSe single quantum wells by magneto- luminescence experiments. The binding energy of the trion singlet ground state is about 2.7 meV. Additionally, an excited triplett state of the trion was detected being stable at magnetic fields above 3 Tesla. Four wave mixing experiments were performed in order to distinguish the trion singulett ground state from biexcitonic signal contributions
