To achieve the film deposition, solutions containing cationic SnF2 or SnCl2 and anionic Na2WO4 or (NH4)2O\u00b7WO3 precursors have been used. The effect of the solution compositions on the films deposition rates, morphology, composition, and properties was investigated. Possible mechanisms of tin-tungsten oxide films deposition into the pores and on the surface of anodic alumina are discussed. The electro-physical and gas-sensitive properties of nanostructured SnxWyOz films have been investigated. The prepared nanocomposites exhibit stable semiconductor properties characterized by high resistance and low temperature coefficient of electrical resistance of about 1.6 \u00d7 10\u22123 K\u22121. The sensitivity of the SnxWyOz films to 2 and 10 ppm concentrations of ammonia at 523 K was 0.35 and 1.17, respectively. At concentrations of 1 and 2 ppm of nitrogen dioxide, the sensitivity was 0.48 and 1.4, respectively, at a temperature of 473 K. At the temperature of 573 K, the sensitivity of 1.3 was obtained for 100 ppm of ethanol. The prepared nanostructured tin-tungsten oxide films showed promising gas-sensitivity, which makes them a good candidate for the manufacturing of gas sensors with high sensitivity and low power consumption.<\/jats:p>","DOI":"10.3390\/s21124169","type":"journal-article","created":{"date-parts":[[2021,6,17]],"date-time":"2021-06-17T11:20:26Z","timestamp":1623928826000},"page":"4169","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Spatially Ordered Matrix of Nanostructured Tin\u2013Tungsten Oxides Nanocomposites Formed by Ionic Layer Deposition for Gas Sensing"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4643-8185","authenticated-orcid":false,"given":"Gennady","family":"Gorokh","sequence":"first","affiliation":[{"name":"R&D Laboratory of Nanotechnologies, Belarusian State University of Informatics and Radioelectronics, 220013 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Bogomazova","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Technology of Electrochemical Production and Electronic Materials, Belarusian State Technological University, 220006 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9453-7575","authenticated-orcid":false,"given":"Abdelhafed","family":"Taleb","sequence":"additional","affiliation":[{"name":"Chimie ParisTech, Institut de Recherche de Chimie Paris, Paris Science & Lettres (PSL) University\u2014CNRS, 75005 Paris, France"},{"name":"Sorbonne Universit\u00e9, 75231 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valery","family":"Zhylinski","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Technology of Electrochemical Production and Electronic Materials, Belarusian State Technological University, 220006 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timur","family":"Galkovsky","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Technology of Electrochemical Production and Electronic Materials, Belarusian State Technological University, 220006 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Zakhlebayeva","sequence":"additional","affiliation":[{"name":"R&D Laboratory of Nanotechnologies, Belarusian State University of Informatics and Radioelectronics, 220013 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei","family":"Lozovenko","sequence":"additional","affiliation":[{"name":"R&D Laboratory of Nanotechnologies, Belarusian State University of Informatics and Radioelectronics, 220013 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Iji","sequence":"additional","affiliation":[{"name":"R&D Laboratory of Nanotechnologies, Belarusian State University of Informatics and Radioelectronics, 220013 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Fedosenko","sequence":"additional","affiliation":[{"name":"R&D Laboratory of Nanotechnologies, Belarusian State University of Informatics and Radioelectronics, 220013 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valeri","family":"Tolstoy","sequence":"additional","affiliation":[{"name":"R&D Laboratory of Programmable Layer-by-Layer Synthesis of Multinanolayers of Hybrid Compounds, St. Petersburg University, 199034 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9635","DOI":"10.3390\/s120709635","article-title":"A Survey on Gas Sensing Technology","volume":"12","author":"Liu","year":"2012","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"206","DOI":"10.1016\/j.mseb.2017.12.036","article-title":"Semiconductor metal oxide gas sensors: A review","volume":"12","author":"Dey","year":"2018","journal-title":"Mater.
