The samples have trigonal structure corresponding to LiYF4 host. The spectral and kinetic characteristics of the synthesized nanoparticles corresponded to the characteristics of the target LiYF4:Nd3+ bulk crystal. In particular, the luminescence decay curves for the 4F3/2 →4I11/2 radiative transition (Nd3+) are single-exponential and the decay times were around 517 μs, which is typical for Nd3+ in LiYF4 host. It has been established that the decrease in the power density of laser radiation energy leads to the increase of the average particle size</p></abstract><trans-abstract xml:lang="ru"><p>В настоящей работе методом лазерной абляции в жидкости (водный раствор этанола) были успешно синтезирована серия кристаллических наночастиц LiYF4:Nd3+ со средним размером около 35 нм. Образцы имели тригональную структуру, соответствующую матрице LiYF4. Спектральные и кинетические характеристики синтезированных наночастиц соответствовали характеристикам монокристалла LiYF4:Nd3+, выступавшего в качестве мишени. В частности, затухание люминесценции на переходе 4F3/2 → 4I11/2 Nd3+ описывалось экспоненциальным законом с характеристическим временеи около 517 мкс, что характерно для ионов Nd3+ в кристалле LiYF4. Установлено, что уменьшение плотности мощности лазерного излучения приводит к увеличению среднего размера частиц.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная абляция</kwd><kwd>лазерная абляция в жидкости</kwd><kwd>наночастицы LiYF4</kwd><kwd>синтез наночастиц с ионами Nd3+</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser ablation</kwd><kwd>laser ablation in liquids</kwd><kwd>LiYF4 nanoparticles</kwd><kwd>Nd3+ nanoparticle synthesis</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was funded by the subsidy allocated to Kazan Federal University for the state assignment in the sphere of scientific activities: FZSM-2023-0012.</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">Compagnini G., Scalisi A.A., Puglisi O.
