Синтезированная смесь жидкокристаллических (ЖК) наночастиц охарактеризована с использованием рентгеновской дифракции (РД), сканирующей электронной микроскопии (СЭМ), инфракрасной Фурье-спектроскопии (ИК-Фурье), УФ-видимой спектроскопии и поляризационной оптической микроскопии (ПОМ). С помощью РД-анализа определен размер НЧ:Dy3+ в смеси НЧ: ~85.23 нм. Изображения СЭМ подтвердили равномерное распределение НЧ:Dy3+ в смеси ЖК-НЧ. ИК-Фурье-спектроскопия подтвердила наличие функциональных групп, связанных с НЧ:Dy3+ в синтезированном соединении. Оптическая ширина запрещенной зоны, определенная по графику Тауца, увеличилась на 0.62 эВ из-за легирования наночастицами. С помощью ПОМ выявлены фазы как чистых, так и диспергированных наночастицами ЖК-смесей, продемонстрированы минимальные изменения температур нематического перехода. Показано, что синтезированная смесь ЖК-НЧ является превосходным материалом, пригодным для микроволновых применений. </p></abstract><trans-abstract xml:lang="en"><p>In the current study, the structural and optical characteristics of a binary mixture composed of p-(npropyloxy) benzoic acid (3OBA) and p-(n-butoxy) benzoic acid (4OBA), integrated with varying concentrations (1, 1.5, and 2 wt.%) of Dy3+:Li4Zn(PO4)2 phosphor nanoparticles (NPs), are systematically examined. The synthesized liquid crystalline (LC) nanoparticle mixture was characterized using a range of analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, and polarizing optical microscopy (POM). XRD analysis revealed that the size of the Dy3+-doped phosphor NPs in the LC mixture was approximately 85.23 nm. SEM images confirmed the uniform dispersion of Dy3+-doped phosphor NPs within the LC mixture. FTIR spectroscopy further corroborated the presence of functional groups associated with Dy3+-doped phosphor NPs in the synthesized compound. The optical bandgap determined from Tauc’s plot was increased by 0.62 eV due to doping of nanoparticles. Additionally, POM imaging revealed the phases of both pure and nanoparticledispersed LC mixtures, showing minimal changes in the nematic transition temperatures. Studies confirm that the synthesized liquid crystal nanoparticle mixture is an excellent material useful for microwave applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бинарная смесь</kwd><kwd>легирование Dy3+</kwd><kwd>рентгеновская дифракция</kwd><kwd>сканирующая электронная микроскопия</kwd><kwd>ИК-Фурье-спектроскопия</kwd><kwd>УФ-видимая спектроскопия</kwd><kwd>поляризационная оптическая микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>binary mixture</kwd><kwd>Dy3+ doped</kwd><kwd>X-ray diffraction</kwd><kwd>scanning electron microscopy</kwd><kwd>Fourier-transform infrared</kwd><kwd>UV-Visible</kwd><kwd>polarizing optical microscopy</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">P.
