Synthesis of Sb-S- and Sb-O-containing nanolayers on silica surface by ionlayering

The possibility was investigated of synthesizing Sb-S-containing nanolayers on the silica surface by the method of ion layering, with acetic acid SbCl 3 solutions and gaseous H2S used as reagents. The layers obtained were anal yzed by X-ray photoelectron spectroscopy, X-ray fluorescence microanalysis, spectroscopy of diffuse reflection and transmission in the UV and visible spectral regions, and ellipsometry. Thermally induced transformations of na nolayers were studied in ail, and temperature intervals were determined in which sulfamide is oxidized to give Sb(III) and Sb(V) oxides.
