Abstract
The present invention discloses an amorphous material comprising nickel oxide doped with tantalum that is an anodically coloring electrochromic material. The material of the present invention is prepared in the form of an electrode () having a thin film () of an electrochromic material of the present invention residing on a transparent conductive film (). The material of the present invention is also incorporated into an electrochromic device () as a thin film () in conjunction with a cathodically coloring prior art electrochromic material layer () such that the devices contain both anodically coloring () and cathodically coloring () layers. The materials of the electrochromic layers in these devices exhibit broadband optical complimentary behavior, ionic species complimentary behavior, and coloration efficiency complimentary behavior in their operation.
