One-step preparation of UV transparent highly ordered mesoporous zirconia thin films

Highly ordered mesoporous ZrO<inf>2</inf> thin films were prepared by evaporation induced self-assembly. Complexing agents and low pH were simultaneously employed in order to control the hydrolysis-condensation kinetics, permitting to cast films in one step. Many commercially available P...
