Enhanced Electroluminescence of Poly(2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene) Films in the Presence of TiO2 Nanocrystals

We demonstrated that in a nanocrystalline TiO2/poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) composite, electroluminescence of this composite is enhanced via addition of TiO2 nanoneedles. The TiO2 nanoneedles enhance the partial crystallization of MEH-PPV around TiO2, wh...

Summary:We demonstrated that in a nanocrystalline TiO2/poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) composite, electroluminescence of this composite is enhanced via addition of TiO2 nanoneedles. The TiO2 nanoneedles enhance the partial crystallization of MEH-PPV around TiO2, which in turn causes a decrease in the hole barrier height and an increase in hole mobility. The I-V measurement was established on an indium tin oxide/MEH-PPV:TiO2/Al device to identify the electrical properties of the composites.
