ABSTRACT:
Aqueous mineralizer solutions having retrograde solubility for ZnO contain a mineral acid in which ZnO is soluble and at least one compound of a coordinating ligand for Zn2+ions wherein the coordinating ligand compound is present in an amount that is effective to inhibit Zn(OH)+ion formation as ZnO is dissolved in the solution. Reduced temperature methods using the mineralizer solutions to grow pure or doped ZnO crystals, pure or doped ZnO thick or thin films, and pure or doped ZnO crystalline powders are also disclosed. Cation doped ZnOs prepared by the inventive methods are also disclosed.
