摘要

迄今为止，LuAG:Ce晶体是最常见的闪烁体之一，因为它们已经被发现很长时间了，并且有大量生产大容量晶体的技术。然而，这种晶体的闪烁特性可以通过制造混合晶体来改善，其中一些离子被其他离子取代。在本工作中，基于生长的LuYAG:Ce无机晶体制备了复合闪烁体。对获得的样品进行了光透射、发光、光输出和衰减时间的研究。确定了制备复合闪烁体的最佳条件和晶粒尺寸。

CREATION OF COMPOSITE SCINTILLATORS WITH A SHORT DECAY TIME

To date, LuAG:Ce crystals are one of the most common scintillators, since they have been known for a long time and there are technologies for mass production of large-volume crystals. However, the scintillation properties of such crystals can be improved by creating mixed crystals with the replacement of some ions by others. In this work, composite scintillators based on the grown LuYAG:Ce inorganic crystals were produced. For the obtained samples, studies of optical transmission, luminescence, light output, and decay time were carried out. The optimal conditions and sizes of crystalline grains for the creation of composite scintillators have been determined.
