Synthesis and study of cerium(IV) polytungstate nanolayers

For the first time the conditions for the synthesis of cerium(IV) polytungstate nanolayers on the silicon surface by the method of ion layering were defined. The layers were studied by scanning electron microscopy, X-ray microanalysis and transmission FT-IR spectroscopy. The synthetized layer is shown to have a globular structure with the size of the globules in the range of 30–50 nm, with the ratio of cerium/tungsten atomic concentrations equal to 0.8.
