A method for preparing an ammonium thiomolybdate-porous amorphous carbon composite superlubricity film is disclosed. First, a porous amorphous carbon film is prepared by an anode layer ion source assisted plasma chemical vapor deposition method and a reactive magnetron sputtering method on a substrate. The porous amorphous carbon film is then impregnated in an ammonium thiomolybdate solution, so that the ammonium thiomolybdate is adsorbed on the porous amorphous carbon film, and the impregnated porous amorphous carbon film is air dried. During the friction process, the composited porous amorphous carbon superlubricity film prepared in the present disclosure promotes the in-situ decomposition of ammonium thiomolybdate to generate molybdenum disulfide by utilizing the friction heat at the initial stage of running-in, further to generate a graphene-like structure under the function of a catalyst, thus realizing a macroscopic super lubricity through a heterogeneous incommensurate contact between graphene and molybdenum disulfide.

The color of an electrochromic stack in a tinted state may be modified to achieve a desired color target by utilizing various techniques alone or in combination. A first approach generally involves changing a coloration efficiency of a WO.sub.x electrochromic (EC) layer by lowering a sputter temperature to achieve a WO.sub.x microstructural change in the EC layer. A second approach generally involves utilizing a dopant (e.g., Mo, Nb, or V) to improve the neutrality of the tinted state of WO.sub.x (coloration efficiency changes). A third approach generally involves tailoring a thickness of the WO.sub.x layer to tune the color of the tinted stack.
