Effects due to magnetic field and the inner core size on the opto-electronic characters of impurity in the CdS/ZnS core/shell quantum dot are investigated. The magnetic field dependent ground state energies and the transition energies of donor impurity in the CdS/ZnS core/shell quantum dot are computed. The oscillator strength, linear, nonlinear and total absorption coefficient and the changes of refractive index are investigated for various values of magnetic field. The results show that the energy difference due to the ground and first excited states is much more sensitive to the strong confinement and the magnetic field. The maximum of absorption peak and the changes due to refractive index are found to enhance with the inclusion of impurity. These properties can be applied in different potential applications based on the intraband optical transitions.
