Определить влияния содержания и форм компонентов люминесцентных веществ со структурой граната (LuAG, YAGG, YAG) и вюрцита (SСASN, СASN) на излучательные свойства белых светодиодов. </p></sec><sec><title>Методы</title><p>Методы. Проведены электронные микроскопические исследования в совокупности с энергодисперсионным и рентгенофазовым анализами порошковых образцов производства ООО «Монокристалл Пасты». Светотехнические параметры определялись с помощью конфокального рамановского и флуоресцентного спектрометра OmegaScope под действием  излучения синего лазера. </p></sec><sec><title>Результаты</title><p>Результаты. Выстроено корреляционное влияние на флуоресцентные спектры состава порошковых материалов со структурой граната (LuAG, YAGG, YAG) и вюрцита (SСASN, СASN), проведен их анализ и описаны перспективные подходы по усовершенствованию структуры белых светодиодов и повышению индекса цветопередачи. Проведен теоретический расчет содержания красного компонента. </p></sec><sec><title>Заключение</title><p>Заключение. Основной задачей светодиодного источника в настоящее время является преобразование синего света полупроводникового кристалла типа InGaN в белый свет в широком диапазоне частот. Белые светодиодные лампы, обладающие многообещающими характеристиками, такими как небольшой размер, безопасность, длительный срок службы и световая эффективность, в скором будущем выступят в качестве альтернативы естественному свету вследствие высокого индекса цветопередачи, характеризующего контрастность отображения предметов облучаемым светом. В результате исследований установлено прямое влияние состава и структуры фотолюминесцентных веществ на излучательные свойства светодиода. Так включением галлия в иттрий-алюминиевый гранат длина волны максимума флуоресценции уменьшается от 547 нм до 523 нм. При замещении в нитридном люминофоре стронция кальцием происходит изменение спектра в сторону красных цветов, а именно с 600 до 650 нм. При многокомпонентном люминофоре, включающем наличие нескольких люминофоров, светодиодный источник способен перекрыть весь диапазон частот видимого излучения и соответствовать естественному освещению.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of research</title><p>Purpose of research. Determine the content and forms of components of luminescent substances with the structure of garnet and nitride on the emissive properties of white LEDs. </p></sec><sec><title>Methods</title><p>Methods. Electron microscopic studies were carried out in conjunction with energy dispersive and X-ray phase analyzes of powder samples, produced by LLC "Monocrystal Paste". Lighting parameters were determined using a confocal Raman and fluorescence spectrometer OmegaScope with blue laser radiation. </p></sec><sec><title>Results</title><p>Results. The correlation effect of physical and mechanical characteristics on the fluorescence spectra of powder materials with the garnet and nitride structure is built, their analysis and promising approaches to improving the structure of white LEDs and the color rendering index are carried out. The theoretical calculation of the content of the red component has been carried out. </p></sec><sec><title>Conclusion</title><p>Conclusion. Offering promising characteristics such as small size, safety, long life and luminous efficiency, white LED lamps perform in a high CRI alternative to natural light, which characterizes the contrast in which objects are displayed by irradiated light. The main purpose of the LED source is to convert the blue light of an InGaN semiconductor crystal into white light over a wide frequency range. As a result of the research, the direct influence of the composition and structure of photoluminescent substances on the emissive properties of the LED has been established. Thus, by including gallium in yttrium-aluminum garnet, the wavelength of the fluorescence maximum decreases from 547 nm to 523 nm. When strontium is replaced in the nitride phosphor with calcium, the shape changes towards red, namely from 600 nm to 650 nm. With a multicomponent phosphor, including both phosphors, the LED source crosses the entire frequency range of visible radiation. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>люминесцирующие материалы</kwd><kwd>светоизлучающий диод</kwd><kwd>рентгенофазовый анализ</kwd><kwd>энергодисперсионный анализ</kwd><kwd>растровая электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>luminescent materials</kwd><kwd>light-emitting diode</kwd><kwd>X-ray phase analysis</kwd><kwd>energy dispersive analysis</kwd><kwd>scanning electron microscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства образования и науки Российской Федерации № 0851-2020-0035.</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Education and Science of the Russian Federation No. 08512020-0035.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">He G., Xu J., Yan H.
