摘要

Thick molybdenum trioxide (MoO_3) films (ca. 120nm) were successfully deposited by an aqueous solution-processed method based on direct dissolution of the powder of ammonium molybdate ((NH_4)_6Mo_7O_(24)·4H_2O) precursors in deionized water. X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) analyses showed that aqueous solution-processed MoO_3 (SMoO_3) has almost the same characteristics as the vacuum-evaporated MoO_3 (eMoO_3). Besides acting as a hole injection material, thicker MoO_3 operated as a short-circuit barrier layer in large-scale organic light-emitting devices (OLEDs). The successful fabrication of 150 × 150 mm~2 lighting panels confirmed the dual function of thick sMoO_3 films in large-area OLEDs.
