Abstract

We have developed new electrical dopants of rhenium oxide ($ReO_3$) and cupper iodide (CuI) as p-dopants and rubidium carbonate ($Rb_2CO_3$) as an n-dopant, respectively. $ReO_3$ has advantage of low temperature evaporation (about $300^{\circ}C$) with enhanced device stability. Various kinds of high performance organic light emitting diodes have been realized, including bottom emission, tandem, and top-emission OLEDs.
