dc.description.abstractWe demonstrated highly efficient devices based on well-known poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] end capped with POSS (MEH-PPV-POSS) polymer by combining of two approaches: (i) inserting of electron transport material (ETM) either between the emissive layer and cathode or into the emissive polymer, and (ii) doping of polymer with quantum dots (QDs). In order to overcome some handicaps, such as interchain interaction and imbalanced charge carrier fluxes, copper indium disulfide (CuInS 2) QDs were incorporated into the polymer matrix, while N-arylbenzimidazoles trimer (TPBi) and 4,7-dipheyl-1,10-phenanthroline (Bphen) were used as ETMs. The best charge carrier balance and color purity were achieved by inserting 0.3 wt% CuInS 2 into the polymer and 40 nm Bphen between the polymer and cathode with a current efficiency of 5.1 cd/A and an external quantum efficiency of 1% which is above the average of literature. © 2012 Elsevier B.V.
