Abstract We investigate the energy level behavior of a nanocrystal system coupled via dipolar interaction under the influence of an external applied magnetic field. The presence of the small dipolar interaction that couples the two corresponding states results in an anti-crossing in the optical spectra. The calculation of the photoluminance intensity signal associated with the anti-crossing levels shows a Lorentz shape with an unusual dip-shape at the zero detuned states by the field strength corresponding to the point at which the crossing would occur in the absence of the dipolar interaction.
