Установлено, что все полученные образцы индатов имели кристаллическую структуру орторомбически искаженного перовскита. В образцах индатов, содержащих ионы Sb3+, присутствовала примесная фаза твердых растворов на основе LaSbO3. Обнаружено, что параметры кристаллической решетки исследованных индатов изменяются незначительно из-за малого содержания легирующих ионов. ИК-спектры поглощения всех полученных образцов индатов отличаются незначительно от ИК-спектров LaInO3. На температурных зависимостях относительного удлинения отсутствуют аномалии, обусловленные фазовыми переходами. Коэффициент среднего линейного теплового расширения составляет (7,26–7,89) · 10–6 К–1. На кривых дифференциальной сканирующей калориметрии не обнаружено никаких тепловых эффектов. Общая потеря массы в интервале температур 300–1265 К не превышает 0,276 мас. %. Полученные результаты показывают, что в интервале температур 400–1100 К исследованные индаты являются термостабильными, что свидетельствует о перспективности их практического применения в широком интервале рабочих температур. </p></abstract><trans-abstract xml:lang="en"><p>La0,95Ln0,05InO3, La0,95Ln0,05In0,98Sb0,02O3 (Ln – Dy3+, Ho3+), La0,90Dy0,05Ho0,05InO3, La0,90Dy0,05Ho0,05In0,98Sb0,02O3 photoluminescent phosphor samples were obtained by solid-phase synthesis. Their crystal structure, FT-IR spectra and thermal expansion were investigated. Complex thermal analysis was carried out for the named indates. All samples were found to have orthorhombically distorted perovskite structure. LaSbO3-based impurity phase was found in indates containing Sb3+ ions. The lattice parameters for all indates vary slightly due to the small content of doping ions. IR-spectra for all samples investigated differ slightly from that for LaInO3. There were no anomalies caused by phase transitions at temperature dependences of elongation. The coefficient of average linear thermal expansion is (7.26–7.89)·10–6 К–1. The curves obtained by differential scanning calorimetry demonstrate no thermal effects. Total weight loss in the temperature range of 300–1265 K does not exceed 0.276 wt. %. These results indicate that all the indates investigated are thermally stable and they are promising for practical application in a wide range of operating temperatures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>индат лантана</kwd><kwd>твердый раствор</kwd><kwd>рентгенофазовый анализ</kwd><kwd>ИК-спектроскопия</kwd><kwd>тепловое расширение</kwd><kwd>термический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lanthanum indate</kwd><kwd>solid solution</kwd><kwd>X-ray diffraction</kwd><kwd>IR-spectroscopy</kwd><kwd>thermal expansion</kwd><kwd>thermal analysis</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">Inorganic luminescent materials: 100 years of research and application / C.
