Tungsten Oxide Metallic Smart Windows Could Function in the Future as Electronics
Tungsten oxide is one of the mostly studied cathodic coloring electrochromic material. Electrochromic property of WO3 has been made into different electrochromic device and is applied in real life. There are many advantages of electrochromic device, transmittance can change continuously in a wide range and can be adjusted manually. A B.C. engineering lab has created metal-coated glass that transmits up to 10 per cent more light than conventional glass and opens the door to windows that function as electronics. The most immediate use of the technology is to create smart window that can be programmed to absorb or reflect heat, depending on the needs of a building’s occupants, said lead investigator Kenneth Chau, a professor at the University of British Columbia Okanagan. “What’s interesting about this discovery is that it’s counterintuitive, because we always think of metals as being opaque, so it runs against our expectations,” he said. “I think one of the most important implicatio...
