Abstract
We fabricated the single layer electroluminescent (EL) devices utilizing poly[2-(carbazol-9-yl)-5-(2-ethylhexyloxy)-1,4-phenylene vinylene] (CzEh-PPV) and poly[2-{4-[5-(4-tert-butylphenyl)-1,3,4-oxadiazolyl]-phenyl}-5-(2-ethylhexyloxy) -1,4-phenylene vinylene] (OxdEh-PPV) doped with varying weight percent of 4-(dicyanomethylene)-2-methyl-6-[p-(dimetnylamino)styryl]-4H-pyran (DCM-1). Field-dependence of the emission spectra of the EL devices was studied in detail: the EL device constructed with CzEh-PPV/DCM-1 reveals a strong field-dependence in its EL spectrum and the emission by DCM-1 is intensified as the applied electric field is increased, whereas the device of OxdEh-PPV/DCM-1 shows an enhanced emission from OxdEh-PPV with increasing field.
