| Popis: | The third order nonlinear optical properties were reported for a new synthesized molecules based on triazepine and thianine, using the third harmonic generation (THG) technique. After synthesis, the powders were deposited on glass substrates using dip coating technique in order get thin films. These thin films were characterized, by different techniques, we mention the absorption and X-ray diffraction. The measurements of third order nonlinear optical susceptibilities were performed on these thin films, using the THG technique at 1064 nm. These investigations were completed by theoretical studies, using energy levels theory HOMO–LUMO and the second order hyperpolarizabilities (γ) results. Good agreement was obtained between the theoretical and experimental results. |
