Abstract
Device performances of green phosphorescent organic light-emitting diodes using
4,4 -N,N -dicarbazole biphenyl CBP and N,N -dicarbazolyl-3,5-benzene mCP as an exciton
blocking layer were investigated. CBP and mCP were introduced between hole transport layer and
emitting layer to block triplet exciton quenching and efficient hole transport to emitting layer. The
efficiency of green devices could be improved by more than three times by using mCP exciton
blocking layer.
