Ferroelectric polymer films are very promising materials for modern microelectronics, molecular electronics and nonlinear optics. Langmuir-Blodgett films of poly vinylidene fluoride copolymer impregnated with organic dye molecules were studied experimentally. Ferroelectric films of this type undergo a phase transition at the Curie temperature. Fluorescence spectra of the structures were investigated. A strong influence of the phase transition onto the position and shape of the fluorescence spectrum was observed. A new effect of photosensitized shift of the Curie temperature was found. Besides the main ferroelectric transition, a low-temperature structural transition in super thin films was discovered for the first time by the optical method. Possible mechanisms of the effects observed are discussed.
