На основании изучения удельной поверхности, микроструктуры и морфологии полученных порошков, а также после прокаливания прекурсоров при темпе- ратурах 700, 900 и 1100 °С установлено, что удельная поверхность падает с повышением температуры прокаливания. Это связано с удалением слабосвязанных примесных групп (ОН, NO, СО2) с поверхности агрегатов, уплотнением кристаллической структуры частиц матрицы и формированием более крупных частиц. При температуре прокаливания 700 °С формируются наноструктурированные частицы размерами от 39 (горение в уксусной кислоте) до 53 нм (горение в сахарозе). При температуре 1100 °С формируются более крупные агрегаты с размерами частиц от 0,6 (при синтезе в сахарозе) до 0,23 мкм (при синтезе в уксусной кислоте). Полученные таким образом порошки проявляют эффективные люминесцентные свойства в красной области спектра при возбуждении в УФ-диапазоне (на длине волны 250 нм). </p></abstract><trans-abstract xml:lang="en"><p>A new approach to the synthesis of nanostructured yttrium oxide powders doped with europium ions by the method of combustionis is described. Carbohydrates (fructose, sucrose) and acetic acid were used as a fuel and hexamethylenetetramine – as additional fuel for ignition of the mixture. Based on the study of specific surface area, microstructure and morphology of the obtained powders, as well as after precursor calcination at 700, 900 and 1100 °C , it was found that specific surface area decreases with the increase of calcination temperature. This is due to the removal of weakly bound impurity groups (ОН, NO, СО2) from the surface of aggregates, compaction of the crystalline structure of the matrix particles and larger particle formation. In case of calcination at 700 °C, nanostructured particles with a size ranging from 39 nm (combustion in acetic acid) to 53 nm (burning in sucrose) are formed. Larger aggregates with particle sizes from 0.6 µm (in presence of sucrose) to 0.23 microns (in presence of acetic acid) are formed at 1100 °C. The powders obtained in such a way exhibit efficient luminescence properties in the red region of the spectrum upon excitation in the UV range (wavelength 250 nm). </p></trans-abstract><kwd-group xml:lang="ru"><kwd>термохимический синтез</kwd><kwd>ультрадисперсные порошки</kwd><kwd>оксид иттрия</kwd><kwd>ионы европия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermo-chemical synthesis</kwd><kwd>yttrium oxide</kwd><kwd>ultrafine powders</kwd><kwd>europium ions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Minh, L.
