| Abstract(in English) | We demonstrate DC-driven hybrid EL devices composed of solution-processed n-ZnO nanocrystal (NC) emission layers and p-pentacene hole-transport layers. The structure of the EL device was glass/ITO/emission layer/pentacene/Al. The emission layer consisting of ZnO NCs with a crystal size of 8 nm was prepared by a screen-printing method. When the ITO-electrode was positively biased over 10 V, the EL emission, consisting of sharp ultraviolet (～380nm) and broad green-yellow (～560nm) spectral components, was observed. We introduced another pentacene layer at the cathode side, and found that the green-yellow component decreased. |
