Using energy dispersive analysis, the qualitative and quantitative composition of the luminophor has been established. To determine the degree of oxidation of manganese ions, the EPR spectra of the luminophor have been studied. The phase composition of the synthesis products has been established by X-ray diffraction, and the luminescent properties have been characterized by the excitation and emission spectra. The influence of the manganese content, as well as the Al : Al2O3 ratio in the charge, on the luminescent characteristics of the synthesized product has been studied.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324404976">Осуществлен самораспространяющийся высокотемпературный синтез образцов люминофора MgAl<sub>2</sub>O<sub>4</sub> : Mn<sup>2+</sup> с использованием теплового эффекта реакции взаимодействия алюминия с перхлоратом натрия. С помощью энергодисперсионного анализа установлен качественный и количественный состав люминофора. Для определения степени окисления ионов марганца исследованы спектры ЭПР образцов люминофора. Фазовый состав продуктов синтеза установлен методом рентгенофазового анализа, люминесцентные свойства охарактеризованы спектрами возбуждения и излучения. Изучено влияние содержания марганца, а также соотношения Al : Al<sub>2</sub>O<sub>3</sub> в шихте на люминесцентные характеристики синтезированного продукта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>luminophor</kwd><kwd>LEDs</kwd><kwd>thermal effect</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>люминофор</kwd><kwd>светодиоды</kwd><kwd>тепловой эффект</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chang M.H., Das D., Varde P.V., Pecht M. // Microelectron.
