Paper Abstract

Electroluminescent (EL) properties of planar light-emitting nanocomposite structures based on gold island films and semiconducting organic polymers poly(p-pheny!enevinylene) (PPV) and aluminum oxyquinoline (the aluminium (III) 8-hydroxyquinoline complex, Alq3) were studied in 400-600 nm spectral range at room temperature. The chemical composition and structureof vacuum deposited PPV and Alq3 films were determined by IR spectroscopy. According to the obtained data, chemical composition of the deposited A1q3 films corresponds to the initial A1q3. The PPV film is formed of oligomers with smaller molecular weight, which are generated in the course of thermal evaporation in vacuum due to decomposition of initial polymer. It was shown that EL spectra of the nanocomposites consist of two bands, one of them being typical of organic molecules, whereas the second one is related to the luminescence of the island film. Therefore, the obtained planar nanocomposite systems can be used as light emitting structures with controllable electroluminescent properties.
