Abstract:
1. A solvothermal method of making nanocrystals comprising dissolving or mixing at least one precursor of said nanocrystals in at least one solvent to produce a solution, and heating said solution to a temperature in the range of greater than a temperature of 250° C. to a temperature of 350° C. to form said nanocrystals, wherein said at least one solvent additionally includes water, and said nanocrystals are comprised of at least one of hafnium oxide, zirconium oxide, hafnium-zirconium oxide and titanium-zirconium oxide, and wherein said precursor is selected from the group consisting of at least one of an alkoxide, an acetate, an acetylacetonate, and a halide, such that when said nanocrystals consists of zirconium oxide, said precursor is not a chloride.
