Abstract
The invention relates to a liquid-phase method for producing metal oxide-containing layers from nonaqueous solution. In said method, an anhydrous composition containing i) at least one metal oxo-alkoxide of generic formula MxOy(OR)z[O(R′O)cH]aXb[R″OH]d, where M=In, Ga, Sn, and/or Zn, x=3-25, y=1-10, z=3-50, a=0-25, b=0-20, c=0-1, d=0-25, R, R′, R″=organic group, X═F, Cl, Br, I, and ii) at least one solvent is applied to a substrate, is optionally dried, and is converted into a metal oxide-containing layer. The invention also relates to the layers that can be produced using the method of the invention and to the use thereof.
Claims13
A process for producing a metal oxide-containing layer, the process comprising applying an anhydrous solution to a substrate, optionally drying a resulting coated substrate and converting a coating formed from said anhydrous solution to form a metal oxide-containing layer, wherein the anhydrous solution comprises:
- i) a metal oxo alkoxide of formula (I):
- MxOy(OR)z[O(R′O)cH]aXb[R″OH]d (I),
- wherein
- x=3-25,
- y=1-10,
- z=3-50,
- a=0-25,
- b=0-20,
- c=0-1,
- d=0-25,
- M=In, Ga, Sn, Zn, or a mixture thereof,
- R, R′, R″ individually represent an organic radical,
- X=F, Cl, Br, or I;
- and
- ii) a solvent.
