Ozone-Mediated Synthesis of Nanostructures

A method of producing nanoparticles, the method comprising:

• providing a gas that includes ozone to a liquid to produce a solution that includes ozone;
• dissolving a metal salt in the solution, the metal salt including at least one of a transition metal or a lanthanide;
• and
• producing at least one of metal oxide nanoparticles, metal oxynitrate nanoparticles, or metal oxyhydroxide nanoparticles from the solution.

A method of producing lanthanide doped cerium oxide nanoparticles, the method comprising:

• dissolving a cerium nitrate in a first liquid to produce a first solution;
• dissolving a lanthanide nitrate in a second liquid to produce a second solution;
• mixing the first solution and the second solution to produce a third solution;
• providing a gas that includes ozone to the third solution;
• and
• producing lanthanide doped cerium oxide nanoparticles from the third solution after ozone treatment.
