Abstract
Lifetime improvement of green phosphorescent organic light-emitting diodes by charge confinement
inside an emitting layer was investigated. Excitons were confined within the emitting layer by using
a charge confining structure with a high doping concentration at the center of the emitting layer. The
lifetime of green devices could be improved by more than five times by confining the excitons at the
center of the emitting layer.
