Образцы приготовлены с помощью наиболее подходящего для крупномасштабного производства метода твердотельной реакции с различными концентрациями ионов Eu3+ и охарактеризованы с помощью рентгеновской дифракции (XRD), сканирующей электронной микроскопии (SEM), инфракрасной спектроскопии с преобразованием Фурье (FTIR), фотолюминесценции (ФЛ) и координат цветности CIE. С помощью XRD показано, что образец является монофазным и кристаллизуется в кубической структуре. Размер кристаллитов ≈82 нм. SEM-изображения при низком разрешении показали образование микростержней, при высоком разрешении — кубическую морфологию. Образование люминофора Ca3Al2O6:Eu3+ подтверждено исследованиями FTIR. Спектры возбуждения ФЛ имеют максимумы при 271 и 396 нм, а излучение ФЛ наблюдалось в диапазоне 500–750 нм для люминофора Ca3Al2O6, легированного ионами Eu3+, с максимумами при 595, 616, 621 и 651 нм с высокой интенсивностью. Люминофор может выступать в качестве единственного источника для красно-оранжевого светового излучения в устройствах отображения. </p></abstract><trans-abstract xml:lang="en"><p>The present paper reports the synthesis and photoluminescence (PL) properties of Eu3+-activated calcium aluminate (Ca3Al2O6) phosphors. The samples were prepared by a conventional solid-state reaction method with different concentrations of Eu3+ ions, which was most suitable for large-scale production. The prepared phosphor sample was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), PL, and CIE chromaticity coordinate techniques. The XRD pattern indicated that the sample was mono-phased and crystallizes in a cubic structure. The crystallite size was found to be nearly 82 nm and the SEM images showed the formation of micro-rods at low resolution and at high resolution exhibited a cube-like morphology. The FTIR studies confirmed the formation of Ca3Al2O6:Eu3+ phosphor. The PL excitation spectra found at 271 and 396 nm and the PL emission was observed in the range 500–750 nm for the Ca3Al2O6 phosphor doped with Eu3+ ions and sharp peaks were found at 595, 616, 621, and 651 nm with high intensity. The present phosphor can act as a single host for red-orange light emission in display devices.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>люминофор Ca3Al2O6:Eu3+</kwd><kwd>рентгеновская дифракция</kwd><kwd>сканирующая электронная микроскопия</kwd><kwd>ИК-Фурье-спектроскопия</kwd><kwd>фотолюминесценция</kwd><kwd>CIE</kwd><kwd>оранжевое излучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ca3Al2O6:Eu3+ phosphors</kwd><kwd>X-ray diffraction</kwd><kwd>scanning electron microscopy</kwd><kwd>Fourier transforms infrared spectroscopy</kwd><kwd>photoluminescence</kwd><kwd>CIE</kwd><kwd>orange emission</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">G.
