| Abstract(in English) | In order to realize high device performance, it is necessary to achieve high efficient of electron injection from cathode. Some research groups have reported thin metals which possess low work function or fluoride-metals used as efficient electron injection cathodes. Furthermore, there are some reports about electron injection mechanisms from cathode. In this study, we focused on the interface between CsF and metals at the cathode, and investigated the effect of the electron injection in polymer light-emitting diodes. From our results, we have confirmed that the efficient injection achieved when the thickness of MgAg which have been deposited on CsF is more than 1nm. Furthermore, we find that the interface exists near the organic layer where the deposition order of CsF and MgAg. In order to achieve efficient electron injection, we figure out that the sufficient device performance is obtained when CsF has been covered with MgAg about 25%. Also, in the case of Mg or Al deposited on CsF, these metals exist on CsF with the thickness of 1nm and the device performance independent of emitting materials as well as MgAg. |
