摘要:

The role of MoO3 in charge generation layers for tandem organic light-emitting diodes is investigated. The electronic structure of a typical MoO3-based charge generation layer, consisting of N, N_-bis_1-naphthyl_-N,N_-diphenyl-1, 1_-biphenyl-4 ,4_-diamine, MoO3, and Mg doped 4,7-diphenyl-1,10-phenanthroline _NPB/ MoO3 /Mg:Bphen_ is identified to be a p/n/n junction. It is shown that MoO3 can pronouncedly modify the energy level alignment, beneficial to charge separation at the NPB/ MoO3 interface and electron injection at the MoO3 /Mg:Bphen interface from MoO3 into suitable molecular energy levels of adjacent emission units. Moreover, Mg:Bphen is favorable to block holes flowing from the anode side directly into the adjacent emission unit.
