We analyse the magneto-photoluminescence of triply negatively charged excitons coupled to a continuum of states. The excitonic complex is confined to a Stranski-Krastanow InAs/GaAs quantum dot embedded in a Schottky diode. Different orientations of the magnetic field have been investigated. A modelling of the Coulomb blockade together with the calculation of the electron Fock-Darwin spectrum has allowed us to predict the magnetic fields of anticrossing between the quantum dot energy states and the wetting layer Landau levels. Good agreement between the theoretical model and the experimental results has been obtained.
