【Abstract】 : Superlattices consisting of alternating layers of organic/polymeric materials have been prepared from tris(8-hydroxyquinoline)aluminum (Alq3) and Poly(N-vinylcarbazole)(PVK) by multisource-type high-vacuum organic molecular deposition.The characteristics of superlattice structures are determined by small angle x-ray diffraction,optical absorption and photoluminescence.The electroluminescent devices(ELs) with the superlattice structure have also been fabricated and the emission characteristics are discussed.更多还原
