Abstract
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.
Claims13
An ink for forming a hybrid molybdenum (VI) oxide (MoO3) film on a substrate, the ink comprising:
- an ammonium molybdate;
- at least one inorganic salt different from ammonium molybdate;
- and
- a solvent or a solvent mixture,
- wherein the at least one inorganic salt is a metal halide selected from the group consisting of zinc chloride, zinc bromide, zinc iodide, calcium chloride, calcium bromide, calcium iodide, beryllium chloride, beryllium bromide, beryllium iodide, magnesium chloride, magnesium bromide, magnesium iodide, strontium chloride, strontium bromide, strontium iodide, barium chloride, barium bromide, barium iodide, radium chloride, radium bromide, radium iodide, cadmium chloride, cadmium bromide, cadmium iodide, mercury chloride, mercury bromide, mercury iodide, copernicium chloride, copernicium bromide, and copernicium iodide.
A method for preparing a molybdenum (VI) oxide (MoO3) coating ink, the method comprising:
- mixing a molybdate compound and an inorganic salt in a solution;
- mixing a solution of molybdate compound and an inorganic salt;
- mixing a molybdate compound and a solution of an inorganic salt;
- or
- mixing a solution of a molybdate compound and a solution of an inorganic salt;
- wherein the inorganic salt is a metal halide selected from the group consisting of zinc chloride, zinc bromide, zinc iodide, calcium chloride, calcium bromide, calcium iodide, beryllium chloride, beryllium bromide, beryllium iodide, magnesium chloride, magnesium bromide, magnesium iodide, strontium chloride, strontium bromide, strontium iodide, barium chloride, barium bromide, barium iodide, radium chloride, radium bromide, radium iodide, cadmium chloride, cadmium bromide, cadmium iodide, mercury chloride, mercury bromide, mercury iodide, copernicium chloride, copernicium bromide, and copernicium iodide.
