Abstract

The effectiveness of Cs-derivatives, including cesium carbonate (Cs₂CO₃), cesium fluoride (CsF), and cesium nitrite (CsNO₃), as dopants of tris-(8-Hydroxyquinoline)-aluminum (Alq₃) in organic light-emitting diodes (OLEDs) were investigated via photoemission spectroscopy and current-voltage characteristics. The n-type doping of Cs₂CO₃ in Alq₃ is most effective. In current injection efficiency, the performance of OLEDs with CsF in cathode structures is similar to that with Cs₂CO₃, working well with both aluminum and silver in cathodes. As for CsNO₃, it is effective only with aluminum cathode due to the reaction between aluminum and CsNO₃.
