Claim:
1. A method of forming a plurality of transitional layers with selectable indices of refraction on a substrate, the method comprising: providing a substrate and a plurality of metal oxide precursor pastes, wherein the plurality of metal oxide precursor pastes each include at least one soluble metal complex, a complex-forming agent, and a resin dissolved in a solvent, wherein the complex-forming agent replaces at least one ligand on the metal complex to provide a metal compound that is less likely than the metal complex to oxidize in the presence of water or oxygen; depositing each of the plurality of metal oxide precursor pastes on the substrate to form a plurality of coating layers; and heating each of the plurality of coating layers to burn off the solvent and the resin, and oxidize the at least one soluble metal complex to thereby form a plurality of transparent transitional layers of metal oxide situated on top of one another on the substrate.
