We demonstrate that by using polyaniline (PANI) or a combination of and indium/tin oxide (ITO) as the transparent anode polymer light-emitting diode with poly[2-methoxy-5-(2′-ethyl- hexyloxy)-1,4-phenylene vinylene] (MEH-PPV), active layer, device performance can be significantly improved. The operating voltage reduced ∼30%–50% quantum efficiency increased ∼30%–40% respect to devices ITO alone hole-injecting anode. barrier height at PANI/MEH-PPV interface is estimated ∼0.08–0.12 eV,...
Three derivatives of poly(paraphenylene) (PPP) have been synthesized, all with excellent solubility in common organic solvents. Efficient blue polymer light-emitting diodes (LEDs) are demonstrated using these PPPs as the semiconducting and luminescent polymers. Double-layer LEDs (consisting a hole transport layer addition to electroluminescent layer) emit light external quantum efficiencies between 1% 3% photons per electron, when indium tin oxide anode calcium cathode. Using internal field...
Light-emitting diodes (LEDs) of poly(2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene) were fabricated using high surface area hole-injecting network electrodes made in situ from blends polyaniline (PANI) low molecular weight polyester resin. Due to the interface between PANI and active luminescent layer enhancement local electric field at rough network, charge carrier injection was significantly improved. LEDs electrode have lower device operating voltage, higher quantum efficiency,...
We report the use of an oxadiazole-containing polymer, poly(phenylene-1,3,4-oxadiazole- phenylene-hexafluoroisopropylidene) (PPOPH), as electron injection layer in polymer light-emitting diodes. By introducing a PPOPH between cathode (aluminum) and luminescent (poly(2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene), device performance was significantly improved; quantum efficiency increased by factor 40, close to that same using calcium cathode. utilizing porous polyaniline network...
Summary form only given. We, demonstrate that by using polyaniline (PANI) or a combination of PANI and Indium/tin oxide (ITO) as the transparent anode polymer light emitting diode widl poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene), (MEH-PPV), thc active layer, device performance can be significantly improved. The operating voltago reduced - 30-50% quantum efficiency increased 30-40% with respect to devices ITO alone the, hole-injecting anode.,The barricir height at PANVWH-PPV...
