Popis:	We demonstrate light emitting devices based on ZnO nanoparticles and realized without any additional organic support layers. Pure ZnO devices showed electroluminescence in the visible and the UV spectral range at voltages below 10 V. In order to facilitate hole injection and to stabilize device operation, additional p-type inorganic support layers were introduced. Sputtered NiO layers are shown to improve the stability of the device and its I/V behavior. First bilayer devices consisting of a layer sequence of p-doped Si and naturally n-doped ZnO nanoparticles revealed promising electro-luminescence results with a high contribution in the UV spectral range at reduced current densities.
