Method of preparing molybdenum oxide films

摘要

Present invention relates to methods of preparing molybdenum oxide inks and molybdenum oxide films, and use of the molybdenum oxide films as hole-transporting layers in optoelectronic devices. The ink for forming a hybrid molybdenum (VI) oxide (MoO3) film on a substrate comprises an ammonium molybdate, at least one inorganic salt different from ammonium molybdate, and a solvent or a solvent mixture.
