%X According to the relationship of Wang and Zunger between the declectric constants and the radius of a CdSe quantum dot (QD),we use the variational method to calculate the binding energy and ground state energy of an exciton in the QD.Compared with the previouse calculations,the present result shows that the binding energy increases while its ground state energy becomes lower and it is close to the experimental value.
