摘要：

Performance of the mixed poly (3-hexylthiophene) (PHT) Langmuir-Blodgett (LB) films on hole-injection for organic electroluminescent (EL) devices was investigated. Onset voltage of EL devices using PHT LB films decreased with increasing number of layers because of reduction of energy barrier of hole injection from indium-tin-oxide (ITO) anode to PHT films. Current efficiency was improved at the monolayer PHT LB film EL devices.
