Abstract
The new photoferroelectric material is prepared by means of dye sensitization of ferroelectric vinylidene fluoride trifluoroethylene copolymers VDF/TrFE. The photoconductivity and bulk photovoltaic effects have been observed in the spectral bands connected with dye molecules absorption. At the ferroelectric phase transition the sharp changes of absorption and fluorescence spectra of sensitized films VDF/TrFE are revealed. These effects are denoted as structural optic effects. The influence of an external electric field on the fluorescence of VDF/TrFE doped by rhodamine 6G is revealed. This phenomena is explained by the influence of polarization on the radiationless electron transitions in the dye molecules.
