　　The energy levels and binding energies of hydrogenic impurity associated with the ground state and some low-lying states in GaAs/AlGaAs core/shell quantum dots are theoretically studied by using the finite difference method.It is shown that energy levels and binding energies are depended dramatically on the size of the quantum dot due to quantum size effect.
