An electrochromic layer, a coated article having the electrochromic layer, and method for making the coated article are provided. The electrochromic layer is made of wolframium oxide doping with A material. The A material may be one or more metals selected from a group consisting of molybdenum, niobium, and titanium. The atom percentage of the A material is about 4 to 12%. When a volt of about 2.1 to 2.8V is loaded on the electrochromic layer, the electrochromic layer turns blue. The electrochromic layer is made of wolframium oxide doping with A material, a reversibility of the electrochromic layer is improved. |
