Thin polyphenylene vinylene electrophoretically and spin-coated films - photoelectrical properties

Popis výsledku v původním jazyce

Electrophoretic deposition (EPD) and spin coating (SC) techniques were compared on poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1,4-phenylene vinylene] (MDMO-PPV) used as a model material. Absorption spectra measured in a toluene solution and a toluene/ acetonitrile suspension with the same MDMO-PPV concentration of 0.0033 g.l-1 were analysed. An observed broadening of the characteristic absorption peak could be related to the formation of tightlyfolded polymer chains in the suspension. Thin films of about300 nm thickness were prepared by EPD from suspension and SC from solution with a concentration of 0.0033 g.l-1 and 8.95 g.l-1, respectively. The ITO|MDMO-PPV|Al structures with EPD MDMO-PPV films behave as a photovoltaic cell, while the same sample configuration with SC MDMO-PPV films acts more like a photoresistor. EPD and SC films exhibit the same charge-carrier photogeneration mechanism. It was clearly demonstrated that the EPD method uses the deposited material more efficiently, pr
