Abstract

Abstract: The dye TPB molecules were successfully fabricated into the polymer ESfilms with superlattice structure. The periodical structure of the multilayer films was determined by small angle X-ray diffraction, the period of 5. 8 nm was calculated according to the Bragg equation. It indicated that each periodical structure consists of two layers of LBfilms and the multilayer films have well ordered layer structure. The PLand ELspectra of the polymer/ dye multilayer films showed that the emission peaks of PLand ELshifted to short wave length relative to its bulk material due to the excitons confinement effects.

Key words: Superlattice, Photoluminescence, Electroluminescence, LB film
