The electroluminescence (EL) produced by a highly luminescent phosphorescent dye Cu_4(C≡CPh)_4L_2 (L = 1.8-bis(di-phenylphosphino)-3, 6-dioxaoctane, Cu_4) doped polymer as emitting layer is reported. The effects o f the chargeinjection balance on the polymers, in particular, poly(N-vinylcarbazole) (PVK) have been studied by usingphotoluminescence and elecholuminescence spectroscopy. Changes in the emission spectra demonstrate the influence of thecharge injection balance on the formation ratio of triplet and singlet excitons. (This provides a new technical approach torealize the color patterning in polymer LEDs.
