Abstract
Low transparency, or colored, copper oxide is taught as a new electrochromic material, in combination with a metallic oxide. The material is formed by application of the copper oxide to a substrate followed by application of the metallic oxide. A low-E glass substrate is heated, and cupric acetylacetonate powder is sprayed at the glass; the cupric acetylacetonate powder is atomized with dry oxygen. The glass/SN.sub.N O.sub.2 F/Cu.sub.x O system is then re-heated. After reheating, tungsten hexachloride dissolved in N,N-dimethyl formamide is sprayed at the copper oxide on the substrate. In a sample material, visible transmission is improved from 33% for copper oxide alone, to 65%.
