Abstract

We have studied the effect of the hole transporting layers on the device efficiencies blue phosphorescent organic light emitting diodes (PHOLED) with of iridiumIIIbis4,6-di-fluorophenyl-pyridinato-N,C2picolinate (FIrpic) doped 3,5--N,N-dicarbazole-benzene (mCP) host. The highest efficiency of blue PHOLED is strongy dependent on the hole transporting materials, exhibiting the maximum current efficiency.
