摘要：

The authors develop an aqueous solution-processed hole injection layer, MoO₃ doped copper phthalocyanine-3,4’,4’’,4’’’tetra-sulfonated acid tetra sodium salt (TS-CuPc), in organic light-emitting diodes (OLEDs) via an environmentally-friendly and easy fabricating process. The generation of charge transfer complex in TS-CuPc:MoO₃ composite films are confirmed by absorption spectra and the X-ray photoemission spectroscopy (XPS) measurements. Enhanced hole injection in OLEDs is attributed to the decreased hole barrier at the ITO side, which is agreed with the Schottky thermal emission evaluation. The efficient modifications of ITO by TS-CuPc:MoO₃ is further confirmed by the ultraviolet photoemission spectroscopy (UPS) measurements.
