Abstract

Electrochromism effect in the nickel compounds has excited a recent interest. Here, the properties of films obtained by two different preparation techniques : anodic oxidation and e^- beam evaporation are studied and compared. The kinetics of colour changes are studied by multichannel optical analysis (OMA), in view to determine if the optical response of this new system can really become usable. Raman spectroscopy is used to determine the chemical and crystallographic natures of the colored and bleached states. In particular, this technique has proved that, contrarily to the hypothesis generally done up to now, the bleached state is Ni0_x and not an hydrated state as Ni(OH)₂.
