Patent ID: 8668774

Claim:
A method of fabricating ZnO, comprising: (a) using an aqueous solution composition to dissolve a zinc containing nutrient at a first temperature, wherein the aqueous solution composition contains one or more sources of complexing ligands, has an appropriate pH, and otherwise comprises a composition that results in the formation of soluble zinc-ligand complexes, wherein the complexing ligands and the formation of the soluble zinc-ligand complexes increases the ZnO solubility in the aqueous solution composition at the first temperature; and (b) synthesizing the ZnO at a second temperature, wherein the second temperature at which the ZnO is synthesized is higher or warmer than the first temperature at which the nutrient is dissolved, and the synthesis of the ZnO is caused by a reduction in solubility of the ZnO in the aqueous solution composition at the second, warmer, temperature compared to the first, cooler, temperature as a result of the complexing ligands having a greater impact on ZnO solubility at the first temperature than at the second temperature.
