Effect of concentration of 3,5,7,3’,4’-pentahydroxyflavone on nonlinear properties of doped epoxy polymers

Abstract

These Epoxy polymer doped with a natural chromophore 3,5,7,3’,4’-pentagydroxyflavone (quercetin) at different concentrations of the dopant. Spectral characteristics and nonlinear optical properties of the polymer materials were studied by UV-vis and FTIR spectroscopy. Morphology of the doped polymer films was observed using scanning electronic microscopy. Quadratic second susceptibilities of the obtained polymer films were calculated according to one-dimensional, rigid oriented gas model. It is shown that the morphology and non-linear properties of the doped polymer films are directly dependent on the dopant concentration.
