We assume that the LUMO of the dispersed in NPB is equal to that of pristine due to the similar polarization of in and in NPB (see Ref. 11). The dashed arrows show that holes on the HOMO states of NPB transfer to the adjacent NPB under operation voltage.

Abstract

A -type doped organic layer combined with a hole-blocking layer has been experimentally demonstrated to serve as the charge generation unit in tandem-type organic light-emitting devices. The -type layer functions as the source of both holes and electrons. Charge separation is explained by the tunneling model that the hole-blocking layer reduces the energy barrier for the electronsgenerated in the -type layer to tunnel through into one light-emitting unit, while the holes generated in the -type layer can transport to the other light-emitting unit easily under operation voltage.
