摘要：

Photoluminescence from organic superlattice structures with 8-hydroxyquinoline aluminum (Alq(3)) and aromatic diamine (TPD) has been studied in terms of the excitation power density of third-harmonic-generation (THG) light from a Nd:YAG laser and the layer thickness of superlattice structures. The photoluminescence intensity from the Alq(3) layer is enhanced with decreasing layer thickness of TPD in a superlattice structure independent of the excitation power density. With increasing excitation power density, the photoluminescence intensity from the TPD layer is enhanced compared with that from Alq(3). The mechanism of nonlinear photoluminescence emission from Alq(3) and TPD superlattice structures is discussed, taking the energy transfer and the interaction of excitons in the superlattice structure into consideration.
