Abstract
Abstract A mixture of carboxylate and diketonate coating reactants is disclosed to form a metal oxide film with essentially the same reflectance and transmittance properties as a metal oxide film formed from diketonate coating reactants alone, while providing improvement in the control of defects in the film.
