Claim Text:
1. A method of making zirconia nanocrystals comprising dissolving or mixing precursors of said zirconia nanocrystals in at least one solvent to produce a solution for synthesis of said zirconia nanocrystals, at least one of heating and increasing pressure of said solution, and reacting said precursors in said solution to form said zirconia nanocrystals in said solution, wherein said zirconia nanocrystals in a dispersion solvent in an amount of 10% by weight produce a dispersion having a minimum transmittance of larger than 15% over a wavelength range of 400-700 nm, when measured in a cuvette with a 10 mm path length, wherein said dispersion solvent is not water and said precursor is not zirconium chloride.
