Подобное дорадиационное тепловое воздействие на нанокристаллы фторида лития приводит к образованию прикластерных агрегатных центров окраски во время радиационного облучения образцов. Установлено, что различия в дорадиационном тепловом воздействии на образцы сказываются на кинетике роста концентраций агрегатных прикластерных центров в пострадиационный период. Сделаны выводы о механизме и процессах образования нанокластеров в образцах, а также о дефектах, участвующих в образовании.</p></abstract><trans-abstract xml:lang="en"><p>It is shown that the ratio of concentrations of near-cluster and conventional radiation color centers increases in magnesium fluoride nanocrystals in the case when the manufactured samples before irradiation are kept for some time at a temperature higher than the anion vacancies mobility temperature. Such preirradiation heat exposure on lithium fluoride nanocrystals leads to the formation of near-cluster aggregation color centers during radiation exposure of the samples. It is established that differences in pre-irradiation thermal effects on the samples affect the kinetic of concentration growth of aggregate near-cluster centers in the post-radiation period. Conclusions are made about the mechanism and processes of nanoclusters formation in the samples, as well as about the defects involved in the formation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фториды магния и лития</kwd><kwd>нанокристаллы</kwd><kwd>радиационные точечные дефекты</kwd><kwd>дорадиационное тепловое воздействие</kwd><kwd>нанокластеры</kwd><kwd>фотолюминесценция</kwd><kwd>дифракция рентгеновских лучей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnesium and lithium fluorides</kwd><kwd>nanocrystals</kwd><kwd>radiation point defects</kwd><kwd>pre-irradiation heat exposure</kwd><kwd>nanosized clusters</kwd><kwd>photoluminescence</kwd><kwd>X-ray diffraction</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">F.
