The ratio of concentrations of nearcluster and conventional color centers increases in magnesium fluoride nanocrystals when prepared samples are maintained for some time before irradiation at a temperature higher than the temperature for mobility of the anion vacancies. Such pre-irradiation treatment of lithium fluoride nanocrystals leads to the formation of near-cluster aggregation of color centers during radiation exposure of the samples. Differences in the preirradiation temperature regimes of the samples affect the kinetics of the growth of the concentration of aggregate nearcluster centers in the post-radiation period. Conclusions are drawn concerning the mechanism and processes of nanocluster formation in the samples as well as the defects involved in their formation.

当将制备的样品在高于阴离子空位迁移率的温度下照射之前保持一段时间后，氟化镁纳米晶体中近簇和常规色心的浓度之比增加。氟化锂纳米晶体的这种预辐射处理导致在样品的辐射暴露期间色心的近簇聚集的形成。样品在辐照前的温度范围的差异会影响辐照后时期聚集附近簇中心浓度增长的动力学。得出有关样品中纳米团簇形成的机理和过程以及其形成中所涉及的缺陷的结论。
