Show affiliationsThe blue electroluminescence from titania nanotubes doped into poly(2-methoxy-5-(2-ethyl hexyloxy)-p-phenylene vinylene) (MEH-PPV) was studied. The results of absorption and photoluminescence demonstrated that the observed blue electroluminescence in the nanocomposites comes directly from band-to-band transitions of titania nanotubes. The relative intensity of the blue electroluminescence was enhanced by increasing the content of titania nanotubes. Moreover, polymer light-emitting diodes doped with titania nanotubes showed higher carrier transport ability and lower onset voltages. Electroluminescence from one-dimensional materials has potential applications in nanoscale electrical and optoelectronic devices.
