Abstract

The results of photorefractivity studies in newly developed polymer composite C₆₀/PVK/DEANST are presented. The composite containinsfullerene (C₆₀) photosensitizing molecules, second-order active molecules of diethylaminonitrostyrene (DEANST) and charge transporting polymeric matrix of poly[N-vinylcarbazole] (PVK). Photorefractive properties of the material were investigated using erasable volume holography and two-beam coupling techniques. Additional information was obtained from the results of photoconductivity, electro-optic modulation and the angular dependence of holographic diffraction. The kinetics of the effect, as well as the writing beams and the external dc field switching of the refractive grating are discussed. A previously developed theory of space-charge field gratings formation in photoconductive polymers is used to calculate four-wave mixing diffraction efficiency.
