; ; ; ; ;
Reflectance-modulated Smart Glass Windows (or smart windows) is a potentially important application for electrochromic thin films. The question addressed in this paper is, what is the upper bound for the near infrared reflectivity modulation in Li{sub x}WO{sub 3} films Based upon recent research on bulk crystals of Na{sub x}WO{sub 3} and bulk crystals and thin films of polycrystalline Li{sub x}WO{sub 3}, it is concluded that the upper bound is probably close to that of bulk crystals of Na{sub x}WO{sub 3} (x > 0.5) for which near infrared reflectance >90% has been reported. 9 refs., 7 figs.
