Abstract: (1601 Views)
In this research, microscopic linear and nonlinear optical properties of an azo dye in two different forms in solvent environments with different dielectric constant was investigated. For this reason, both DFT and spectroscopic methods have been used. The results indicate that molecular linear and nonlinear optical properties depend highly on the molecular structure and the properties of molecular surrounding environment. In this case, the maximum linear polarizability and first and second order hyperpolarizability were observed in azo form of molecule in DMSO with high dielectric constant. Therefore, by proper selection of molecular surrounding environment, it is possible to increase its linear and nonlinear optical properties.
Keywords: Azo, First order hyperpolarizability, Linear Polarizability, Second order hyperpolarizability.
