Abstract
Organic electroluminescent (EL) devices with multilayer structure were fabricated using alkaline metal compounds as the electron injection materials. We found that the EL cells using the alkaline metal compounds reduce the driving voltage and increase the quantum EL efficiency. In addition, these cells are made with good reproducibility compared with the cells using aluminum and lithium alloy cathode.Keywords
