A novel method has been studied for fabricating printed low-work-function aluminum (Al) films. It was used an Al precursor ink, OAlH3 (C2H5)2, which can easily decomposed into Al and H2 at normal pressure and low temperature (80℃) with the catalyst of TiCl4. Compared with the high consumption methods, such as sputtering, thermal evaporation, chemical vapor deposition, the printed Al pattern can produce various rectification properties of electrical sheet resistances (2.29 Ω/□) and work function (3.76eV), which can be well applicable to the fabrication of cathode materials of OLEDs.
