Abstract The third order nonlinear optical susceptibility is investigated within the frame work of the effective-mass approximation, for the ZnS/CdS/ZnS quantum dot-quantum well. The numerical results revealed that the position and the intensity of the susceptibility peaks can be modulated by varying core or shell radius. With increasing the width of shell, the peaks are redshifted and the intensities are intensified, the ZnS core size has also a crucial impact on nonlinear susceptibility. The obtained results can serve the photonic and optoelectronic fields.
