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 applied voltage 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 with applied voltage.
