EMISSION CHARACTERISTICS OF ORGANIC LIGHT-EMITTING DIODES WITH A HETEROSTRUCTURE OF DYE DOPED POLY(N-VINYLCARBAZOLE)/TRIS(8-HYDROXYQUINOLINE) ALUMINUM
Organic electroluminescent diodes with a heterostructure of 9,10-bis（phenylethnyl） anthracene（BPEA） doped poly（N-vinylcarbazole） （PVK）/tris（8-hydroxyquinoline）aluminum （Alq3） have beenfabricated. The electroluminescence （EL） both from BPEA and Alq3 were observed when the Alq3 layer isthin enough. With increasing thickness of the Alq3 layer, the relative emission intensity of BPEA is graduallydecreased. For the thin Alq3 layer structure, the light emission of Alq3 becomes more dominant as the appliedvoltage increases. It is proposed that the electron-hole recombination takes place in both PVK and Alq3 films.The field-induced quenching theory has also been applied to explain the change of the EL spectra withapplied voltage.
