The binding energy of excitons confined to a quantum ring under the influence of perpendicular homogeneous magnetic field is calculated as a function of the ring radius.Calculations are made by using the method of exact diagonalization within the effective-mass approximation.The feature of binding energy of the ground state as a function of the ring radius for several values of the magnetic field has been revealed.The interesting feature of our study is that, in a quantum ring,the geometric structure of excitons may reveal transition.
