Abstract

We succeeded in observing electroluminescence (EL) of Tetraphenylpyrene (TPPy) as an active layer in an organic field-effect transistor (OFET). In particular, an OFET with a short channel of dSD<1.0μm demonstrated higher EL efficiency than one with a much longer channel (dSD>10μm). We observed a maximum EL quantum efficiency (ηmax) of ∼0.3% in the short-channel-length device at an applied source-drain voltage of Vd∼-100 V and a gate voltage of Vg>-50 V. From the OFET characteristics, although the TPPy layer demonstrated typical p-type operation, the occurrence of EL clearly indicated simultaneous hole and electron injection from the source and drain electronics, respectively, under high Vd and Vg.
