Аннотация

Vanadyl and nickel alkoxoacetylacetonates were used to prepare vanadium pentaoxide films doped with 1, 3, and 10 mol % nickel oxide. All films crystallized in tetragonal β-V2O5. The materials are strongly textured along the (200) axis and formed from one-dimensional structures, however, at 3 and 10 mol % NiO content, nanoparticles of 30–50 nm size are also observed in addition to them. According to the results of Raman spectroscopy, the materials contain a noticeable amount of V4+, ions, but no traces of NiO phases were found. All obtained materials, in terms of electrochromic properties are cathodic, changing color during reduction to dark blue, and during oxidation — to more transparent yellow. At the same time, an increase in nickel content leads to a decrease in coloring efficiency and slowing down of electrochromic processes. The results of the study allow us to conclude that it is promising to use materials based onV2O5, doped with nickel, obtained with the use of metal alkoxoacetylacetonates as precursors, as components of electrochromic devices.
