Сформированные наноструктурированные системы изучены с помощью электронной микроскопии, рентгеновского микроанализа и рентгеновской спектроскопии. Нанокомпозиты представляют собой двухслойные системы из пористой матрицы или островковой пленки TiO2, на поверхности которых находятся вертикально ориентированные пластинки Bi2O3. В спектре фотолюминесценции структуры Al2O3/Bi2O3 присутствуют два канала фотолюминесценции с пиками на 460 и 560 нм при 345 нм возбуждения. Анализ EDX-спектров показал, что атомарное соотношение Bi, Ti и O составило 31,46 % Bi : 3,78 % Ti : 51,05 % O. Показана возможность использования сложного нанокомпозита в качестве контрастирующего агента в рентгеновской диагностике и для защиты от ионизирующего излучения.</p></abstract><trans-abstract xml:lang="en"><p>The features of the bismuth oxide deposition by the ion layering method on matrices of anodic alumina and anodic titania have been studied. The formed nanostructured systems have been studied by means of electron micros copy, X-ray microanalysis, and X-ray spectroscopy. Two-layer nanocomposites consist of porous matrix or TiO2 island film with vertically oriented Bi2O3 plates placed on the surface. The photoluminescence spectrum of Al2O3/Bi2O3 oxide structure contains two photoluminescence channels with peaks at 460 and 560 nm upon excitation at 345 nm. Analysis of the EDX spectra showed that the atomic ratio of Bi, Ti and O was 31.46 % Bi : 3.78 % Ti : 51.05 % O. The possibility of using complex nanocomposite as contrast agents in X-ray diagnostics and for protection against ionizing radiation is shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид висмута</kwd><kwd>оксид титана</kwd><kwd>пористый анодный оксид алюминия</kwd><kwd>ионное наслаивание</kwd><kwd>нанокомпозит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bismuth oxide</kwd><kwd>titanium oxide</kwd><kwd>porous anodic alumina</kwd><kwd>ion layering</kwd><kwd>nanocomposite</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность начальнику сектора физико-технического анализа ГЦ «Белмикроанализ» Д.
