A novel electrochromic device utilizing a single film of Prussian blue is described, and its optical switching behavior is characterized. Light transmission through the device can be increased by the application of 2–12V across the film; the larger voltages bleach more of the Prussian blue up to a maximum of about 50%. The device is fully colored in the "off state" and has no optical memory.
