Abstract
Films of NiOxHy were made by reactive dc magnetron sputtering of Ni followed by electrochemical treatment in KOH. Infrared reflectance spectroscopy with obliquely incident ρ-polarized light documented a unique topochemical reaction with the bleached state being β-Ni(OH)2 and the colored state being β-NiOOH. The same technique yielded clear, though not yet fully understood, data on the evolution of electrochromism during potentiodynamic cycling. © 1991, Materials Research Society. All rights reserved.
