In addition, we also investigated the linear and the third-order nonlinear optical absorption coefficients as a function of the incident photon energy for the 1s-1p, 1p-1d and 1d-1f transitions. Our results are shown that the existence of impurity has great influence on optical absorption coefficients. Moreover, the optical absorption coefficients are strongly affected by the incident optical intensity, relaxation time, parabolic potential and dot radius.eninfo:eu-repo/semantics/closedAccessSpherical Quantum DotBinding EnergyLinear and Nonlinear Optical Absorption CoefficientParabolic PotentialArticle28391795180010.1016/j.optcom.2009.12.027Q2WOS:000275917600026N/A
