The diﬀerences betweentechnologies for the synthesis of titanium dioxide were compared. It is experimentally shown that the developed gel technology allows to get almost 100% phase of nanostructured anatase that was conﬁrmed by high-resolution microscopy and X-ray results. The topography and morphology of the ﬁlms samples were investigated. The photoactivity of the synthesized ﬁlms was studied by EPR spectroscopy. It is shown that the photoactivity of the ﬁlms is increased by the UV irradiation. Titanium dioxide was modiﬁed by nanoparticles of gold with various concentrations. Has been investigated the depending of the ratio of the solution components in the manufacture of gel ﬁlms, as well as of the annealing temperature of their formation on transmission spectra. It is shown that the absorption spectra depend signiﬁcantly on the parameters of the technology. A study of the absorption spectra of titanium dioxide ﬁlms containing gold nanoparticles showed signiﬁcant changes in the spectra, exactly, there is an additional absorption peaks of varying intensity and the observed shift in the passband region. These changes are caused, presumably, by changes of the ﬁlm structure, and the aggregation of gold nanoparticles. Studies have shown the prospects of the gel method for the synthesis of titanium dioxide and its modiﬁcation of nanoparticles.</abstract><trans-abstract xml:lang="ru">В работе исследовались физико-химические свойства плёнок диоксида титана, содержащих наночастицы золота, изготовленных по гель-технологии. Проведено сравнение разных технологий синтеза диоксида титана. Экспериментально показано, что разработанная гель-технология позволяет получать практически 100% фазу наноструктурированного анатаза, что было подтверждено методами микроскопии высокого разрешения и результатами рентгеноструктурного анализа. Проведены исследования топографии и морфологии полученных образцов плёнок. Изучена фотоактивность синтезированных плёнок методом ЭПР-спектроскопии. Показано увеличение фотоактивности плёнок при УФ-облучении. Проведена модификация диоксида титана наночастицами золота разной концентрации. Исследованы спектры пропускания в зависимости от соотношения компонент раствора при изготовлении гель-плёнок, а также от температуры отжига при их формировании. Показано, что спектры поглощения существенно зависят от параметров технологического режима. Исследование спектров поглощения плёнок диоксида титана с содержанием наночастиц золота показало существенные изменения спектров, а именно: возникали дополнительные пики поглощения разной интенсивности и наблюдался сдвиг края полосы пропускания. Эти изменения обусловлены, по-видимому, изменением структуры плёнок, а также агрегацией наночастиц золота. Проведённые исследования показали перспективность гель-метода для синтеза диоксида титана и его модифицирования наночастицами.</trans-abstract><kwd-group xml:lang="en"><kwd>sol-gel and gel methods</kwd><kwd>dioxide titanium ﬁlm</kwd><kwd>modiﬁcation</kwd><kwd>nanoparticles</kwd><kwd>gold</kwd><kwd>spectroscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>золь-гель и гель-методы</kwd><kwd>плёнки диоксида титана</kwd><kwd>модификация</kwd><kwd>наночастицы</kwd><kwd>золото</kwd><kwd>спектроскопия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kreibig U., Vollmer M.
