We consider how the weakening of piezoelectric polarization e ects due to the existence of graded interfaces modiÿes the conÿned exciton properties in In0:2Ga0:8N=GaN single quantum wells. The balance between the red shift of the exciton energy related to the enormous polarization electric ÿeld insi
