N2 - Quantum confinement effects have been investigated using nanocrystals of CuBrxCl1-x solid solutions with different composition ratios. The size dependence of the exciton energy exhibits a larger dependence than that expected by the simple confinement model. The results can be explained well taking into account the Coulomb repulsive potential due to the charge localized at the interface. The simple quantum mechanical calculations confirm that the localized charge raises the confinement energy level.
