Claim:
1. A method of manufacturing a thermochromic substrate, comprising: coating a base substrate with a first thin film; coating the first thin film with a pre-thermochromic thin film, the pre-thermochromic thin film comprising a composition having a formula A and x and z are relative molar proportions of the metal A and of oxygen, respectively, wherein z can be zero or greater; coating the pre-thermochromic thin film with a second thin film, wherein each of the first thin film and the second thin film comprises at least one of a transparent oxide thin film or a transparent nitride thin film, the transparent oxide thin film or the transparent nitride thin film comprises at least one selected from the group consisting of silicon dioxide (SiO modifying the pre-thermochromic thin film into a thermochromic thin film having a formula A wherein each refractive index of the first thin film and the second thin film is different from that of the thermochromic thin film.
