Рентгеновская дифракция указывает на их однородную кристаллическую структуру. С помощью сканирующей электронной микроскопии установлено, что образцы имеют большой размер зерна и неправильную, неоднородную форму. Кривая свечения термолюминесценции (ТЛ) записана для оптимизированной концентрации легирующего иона и представляет собой широкую кривую свечения ТЛ с центром при 370°C для образца, экспонированного в УФ-свете. Соответствующие параметры ловушек рассчитаны с использованием метода компьютерной деконволюции кривой свечения. Большинство пиков демонстрируют кинетику первого и общего порядка с коэффициентом формы (µ) в диапазоне 0.313–0.568. Полученный люминофор может быть полезен для применения в ТЛ-дозиметрии. </p></abstract><trans-abstract xml:lang="en"><p>Tb3+-activated lanthanum cerium phosphate (LaCePO4) phosphors are synthesized using the modified solid-state reaction method. X-ray diffraction (XRD) patterns indicate a uniform crystalline structure. Scanning electron microscopy (SEM) images reveal that the samples had a large grain size and irregular, nonhomogeneous shape. The thermoluminescence (TL) glow curve is recorded for an optimized concentration of doping ion, and it shows the broad TL glow curve centred at 370°C for the UV-exposed sample. The corresponding trap parameters are calculated using the computerized glow curve deconvolution (CGCD) technique. CGCD analysis indicates that most of the peaks exhibit first-order and general-order kinetics, with shape factor (µ) values ranging from 0.313 to 0.568. The prepared phosphor may be useful in TL dosimetry applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>LaCePO4:Tb3+</kwd><kwd>твердофазная реакция</kwd><kwd>рентгеновская дифракция</kwd><kwd>сканирующая электронная микроскопия</kwd><kwd>термолюминесценция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LaCePO4:Tb3+</kwd><kwd>Solid-state reaction</kwd><kwd>X-ray diffraction</kwd><kwd>scanning electron microscopy</kwd><kwd>thermoluminescence</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">B.
