摘要：
Photoluminescence from an organic multilayer structure utilizing 8-hydroxyquinoline aluminum (Alq(3)) and aromatic diamine has been discussed in terms of the wavelength of the excitation light and the layer thickness. The photoluminescence intensity from Alq(3) layers is enhanced in the thinner multilayer structure compared with the thicker one as a result of efficient energy transfer at the heterointerfaces. The mechanism behind the increase of photoluminescence intensity in the organic multilayer structure is discussed.
