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