Studies of optical nonlinear properties of asymmetric ionic liquids

Nonlinear refraction and absorption properties to twelve ionic liquids were measured by the Z-scan technique. k/dn/dT value reference was determinate by using only one measure. An Influence of anion and cation to nonlinear optical properties was analysed. Cations with mayor length chain and aromatic...

Description
Summary:Nonlinear refraction and absorption properties to twelve ionic liquids were measured by the Z-scan technique. k/dn/dT value reference was determinate by using only one measure. An Influence of anion and cation to nonlinear optical properties was analysed. Cations with mayor length chain and aromatic systems presented better nonlinear optical properties that the alicyclic cations. [NO3] anion presented the best contribution to these properties independently of cation used. •Linear refraction index, nonlinear refraction index and nonlinear absorption coefficient of twelve ionic liquids.•1-buthyl-3-methylimidazolium nitrate gives best nonlinear to nonlinear refraction index and nonlinear absorption coefficient.•Our model to adjust Z-scan data allows obtain a reference value to k/dn/dT.
