Color-variable electroluminescence from multilayer polymer films

“…The above results may be inconsistent with previous studies: 15,16 i.e., Garten et al have observed a large difference of threshold voltage by bias direction in an ITO/ Poly ͑3-octylthiophene͒/Al EL device. That is, under forward bias condition, the largest barrier is that for the injection of holes from ITO to PPV ͑0.6 eV͒, while under reverse condition there exists a barrier of 1.9 eV for injection of electrons from ITO to PPV as well as that of 1.8 eV for injection of holes from Mg-In to PDT.…”

Development of metal sulfide-poly (3-octylthiophene) composite LB multilayers

“…4(a). The EL peak 580 nm along with a shoulder at 600 nm is attributed to poly(octyl-thiophene) [27][28][29]. The position of the EL peak is however blueshifted from the reported EL peak 660 nm for polyalkylthiophenes [28,29].…”

A Simple Method for Fabricating Polymeric Light-Emitting Diodes

“…The knee-shaped curve is characteristic of diode operation and is similar to that observed for LEDs with vacuum-deposited metal electrodes. 9 Figure 3b illustrates the variation of light emitted with total current passing through the device. 7 The light onset, for LEDs with chemically deposited silver electrodes, was observed at applied fields of 1.4 × 10 6 V/cm, which is slightly higher than that reported for LEDs with vacuum-evaporated silver electrodes.…”
