采用有机分子束沉积法生长了由8-羟基喹啉铝（Alq 3）和芳香族二胺交替层组成的多层结构有机电致发光（EL）二极管。与单层结构相比，多层结构的EL发射显示出光谱变窄，并且已经观察到发射能量向更高的能量移动。讨论了多层膜结构二极管的光谱窄化机理和发射能量漂移。
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.
