摘要：

organic electroluminescent (EL) diode with a multilayer structure which consists of alternating layers of organic 8-hydroxyquinoline aluminum (Alq3) and aromatic diamine has been grown by organic molecular beam deposition. The EL emission from the multilayer structure shows spectral narrowing and the emission energy has been observed to shift to higher energy compared with that in the monolayer structure. Mechanism of spectral narrowing and the emission energy shift in the diode with the multilayer structure have been discussed.
