Исследованы смещения полос люминесценции прикластерных центров при изменении температуры хранения образцов до и после радиационного облучения. Определены сдвиги и ширины полос люминесценции и возбуждения люминесценции после теплового отжига образцов, когда размеры нанокластеров уменьшаются. Найден метод увеличения размера нанокластеров и изучено влияние этого увеличения на спектры исследуемых нанокристаллов.</p></abstract><trans-abstract xml:lang="en"><p>Changes in the luminescence and luminescence excitation spectra of near-cluster radiation-induced color centers in the nanocrystals of sodium, magnesium and lithium fluorides are examined by changing in the sizes of the nanoclusters, near which the centers are localized. Shifts in the luminescence bands of near-cluster centers are investigated with changes in sample storage temperature before or after radiation exposure. Shifts and widths of the luminescence and luminescence excitation bands are determined after thermal annealing of the samples, when nanocluster sizes decrease. A method for increasing nanocluster sizes is developed, and the effect of this increase on the spectra of the nanocrystals is studied.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фториды натрия</kwd><kwd>магния и лития</kwd><kwd>нанокристалл</kwd><kwd>радиационный центр окраски</kwd><kwd>люминесценция</kwd><kwd>смещение спектра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sodium</kwd><kwd>magnesium</kwd><kwd>and lithium fluorides</kwd><kwd>nanocrystal</kwd><kwd>radiation color centers</kwd><kwd>luminescence</kwd><kwd>spectrum shift</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной финансовой поддержке ГПНИ Республики Беларусь “Фотоника и электроника для инноваций”, подпрограммы “Фотоника и ее применение” (задание 1.5).
