Nanowerk  July 19, 2021 An international team of researchers (Australia, China) has developed a plasma-generated, hybrid nanocomposite material which is free of indium. They used high power impulse magnetron sputtering (HiPIMS) technology to deposit the internal WO3 layer and the external Ag/WO3 nanocomposite. High rates of silver ionization in the HiPIMS process and energetic arrival of silver ions on the negatively biased dielectric/metal/dielectric structure enabled their penetration into the external tungsten oxide layer, forming a nanocomposite structure in a single-step process. This nanotechnology-enabled approach allows electrochromic devices to change colour efficiently and rapidly upon a user’s request and offers a […]
