Theoretical and experimental comparative study of nonlinear properties of imidazolium cation based ionic liquids

This work describes the experimental and theoretical investigation of nonlinear optical properties imidazolium cation based ionic liquids corresponding thermo-optical parameters. The results properties, such as refractive index are determined by Z-scan EZ-scan techniques with a femtosecond laser source. Theoretical simulations linear performed density functional theory (DFT) discussed in terms polarizabilities hyperpolarizabilities. A correlation between is presented, where variation signals each liquid can be compared their calculated properties.
