Colloidal cobalt-doped ZnO nanoparticles by microwave-assisted synthesis and their utilization in thin composite layers with MEH-PPV as an electroluminescent material for polymer light emitting diodes
Original language description
CoxZn1-xO (x = 0.01, 0.05 and 0.1) nanoparticles were prepared by microwave-assisted polyol method from zincacetate dihydrate and Co(II) acetylacetonate. The reactions were performed in diethylene glycol (DEG) at 250 °Cwith the use of oleic acid as a surfactant. Resulting nanoparticle (ca. 10 nm) precipitates were washed withmethanol and dried or kept as colloidal solutions redispersed in toluene. Colloidal solutions were mixed with thePoly [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) polymer to produce thin nano-composite layers with specific optoelectronic properties. The electronic structure in terms of density of states(DOS) of MEH-PPV and MEH-PPV/nanocomposite layers was investigated by recently proposed energy resolvedelectrochemical impedance spectroscopy method. The MEH-PPV polymer and its nanocomposites with ZnO orCoxZn1-xO nanoparticles were used as thin active layers in polymer light emitting diodes (PLED). The nano-composite layers exhibited optoelectronic properties which were found to be beneficial as the active layer inPLEDs, exhibiting an order of magnitude enhancement in electroluminescence intensity. A pronounced effect onthe opening bias voltage of final devices with CoxZn1-xO nanoparticles was also observed.
