We calculated the exciton binding energy and energy levels in GaAs=Al0:3Ga0:7As DQWs with non-abrupt interfaces, taking into account the electric and magnetic ÿeld e ects. Numerical results for GaAs=Al0:3Ga0:7As double quantum wells show an enhancement of the e-hh exciton energy by as much as 50 meV
