Abstract

We report room-temperature, white-color electroluminescence in ZnO nanowires embedded solidly in organic thin films. Excitonic luminescence around 380 nm is observed as a shoulder on a broader, defect-related band covering all of the visible range and centered at 620 nm. The ZnO nanowires are grown in a low-temperature process employing a technique that is suitable for large-area applications. The nanowires are robustly encapsulated in organic films deposited from high-molecular-weight solutions. Electron injection occurs through a transparent SnO2 layer, while hole injection is mediated by a p-doped polymer and an evaporated Au-contact.
