We theoretically consider binding of quasi-2D charged excitons X− on isolated donor ions D+ located at various distances from the quantum well. We establish how many different singlet X<sub>s</sub><sup>-</sup> and triplet X<sub>t</sub><sup>-</sup> bound states a donor ion D+ can support in magnetic fields B > 5 T. We show that dark X− states acquire finite oscillator strengths and that shake-up transitions become allowed in photoluminescence in the presence of the D+ ion. ©2007 American Institute of Physics
