Abstract
A chalcone, 1-phenyl-3-(4-dimethylamino phenyl) prop-2-en-1-one (PDAC) was synthesized and the structure was confirmed by FT-IR and single crystal XRD techniques. This chalcone was doped to Poly (Vinyl Alcohol) and films were prepared by solution casting method. The optical studies on pure PDAC and films were carried out with UV-Visible, Z-scan and DFWM techniques. The nonlinear parameters of the samples were obtained by z-scan. An enhancement in NLO response was observed in films. The results were compared with nonlinear parameters obtained with pico second DFWM experiment. The composite is thermally stable up to 298 0C.
