Semiconductor nanoparticles are attractive candidates for future large-area light emitting devices that are both costeffective
and robust. We demonstrate a ZnO nanoparticle light emitting device realised without organic support layers.
Tight layers with subμm thickness were fabricated using commercially available ZnO nanoparticles from the gas phase
and fluorine-doped tin oxide glass as a substrate. After evaporation of a top electrode, a non-linear I-V characteristic was
obtained. At room temperature, the device operates at voltages of only few Volts and shows electroluminescence in the
visible spectral range and a pronounced UV peak related to near-band emission of the ZnO.
