Abstract

We succeeded in observing bright electroluminescence (EL) from 1wt%-rubrene doped tetraphenylpyrene (TPPy) as an active layer in an organic field-effect transistor (OFET) structure. We observed a maximum EL quantum efficiency (ηext) of ∼0.5 % with a Cr/Au source-drain electrode. From the OFET characteristics, although the 1wt%-rubrene:TPPy co-deposited layer demonstrated typical p-type operation, the occurrence of EL clearly indicated occurrence of simultaneous hole and electron injections from the source and drain electrodes, respectively. This device configuration provides novel organic light emitting diode structure where anode (source) and cathode (drain) electrodes are laterally arranged, giving us a chance to control drain current by changing gate bias.
