The results indicate, the ground state energy increased quickly as the decrease of ZnO QD radius, when the radius decreased to the effective Bohr radius of ZnO exciton (aB=1.8nm), the ground state energy is 488meV higher than the conduction band bottom, about 8 times of binding energy of ZnO free exciton. When the radius is larger, the ground state energy inclined to a constant (under conductor bottom about 65meV), approximate the binding energy of the exciton in bulk crystal ZnO.
