Abstract

We report a novel approach that leads to a significant improvement in the performance of transparent polymer light-emitting diodes (TPLEDs). By introducing a solution-based titanium oxide (TiO _x) layer, we have demonstrated that the device performance of TPLEDs using aluminum-doped zinc oxide (AZO) top electrodes is enhanced. The TiO _x layer lowers the energy barrier between the luminescent polymer and the AZO top electrode by modifying the WF of the top AZO electrodes. Moreover, the TiO _x layer prevents the damage caused by UV radiation and by highly energetic ions generated during the AZO sputtering.
