Kurzfassung:
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.
