Electrochromic devices fabricated by layer‐ by‐layer assembly of europium‐containing polyoxometalate clusters, poly(allylamine hydrochloride), and poly(styrenesulfonate) are investigated (see Figure). A high electrochemical contrast, adequate response time, low operation voltage, and low power consumption are reported. A further advantage of these devices is the potential for automating their fabrication.
