Abstract
One exemplary embodiment of an electrochromic thin-film material comprises an alloy of antimony and one or more base metals; and/or an alloy of antimony, one or more base metals, and lithium; and/or an alloy of antimony, one or more base metals, lithium, and one or more noble metals. Another exemplary embodiment of an electrochromic thin-film material comprises a multilayer stack, the multilayer stack comprising at least one layer comprising one of antimony, antimony-lithium alloy, antimony-one or more base metals alloy, antimony-one or more base metals-lithium alloy, antimony-one or more base metals-one or more noble metals alloy, and antimony-one or more base metals-one or more noble metals-lithium alloy; and at least one alternating layer comprising one of a base metal and a base-metal alloy. One or more of the base metals comprise Co, Mn, Ni, Fe, Zn, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W, Cd, Mg, Al, Ga, In, Sn, Pb, and Bi, and alloys thereof.
