摘要

MoO3 and Ca were incorporated in ambipolar 4, $4'$ -N, $\text{N}'$ -dicarbazolylbiphenyl (CBP) by coevaporation as stable inorganic acceptors and donors, respectively. Both charge transport and injection in CBP single-carrier devices were markedly improved as the doping concentration was raised above 10 wt% for MoO3 and 6 wt% for Ca. P-i-n homojunction blue fluorescent organic light-emitting diod...
