摘要：
Films of W-Ce oxide and Ti-Ce oxide were made by reactive DC magnetron sputtering. Li+ intercalation/deintercalation showed that the electrochromic coloration efficiency depended on the Ce/W and Ce/Ti ratio, and at proper values of these ratios the films remained transparent irrespective of their ion content. Ti-Ce oxide combines this property with good electrochemical cycling durability, and this material can serve as a counter electrode in transparent electrochromic devices.
