核能和高能物理研究需要具有高光产额、高密度、快速衰变时间和抗辐射性的新型高性能闪烁体。在本文中,我们提出的晶体生长和结果,从16毫米直径的铈(Ce)掺杂的Tl2LaCl5(TLC)和铕(Eu)掺杂的TlCa2Br5(TCB),以及一英寸直径的铈掺杂的Tl2GdBr5(TGB)和铕掺杂的TlSr2I5(TSI),每个生长在一个两区的垂直炉通过修改的布里奇曼法。从生长的梨晶中提取和处理的样品的特征在于它们的闪烁特性,如能量分辨率、光产额、衰减时间和非比例性。TGB、TLC、TCB和TSI样品在662 keV处的能量分辨率分别为5.1%、3.4%、4.0%和3.3%。Ce掺杂的TGB和TLC具有26 ns和48 ns的单一衰减时间分量,而Eu掺杂的TCB和TSI具有长衰减时间,其主要衰减常数为571 ns和630 ns?当与NaI:Tl和BGO相比时,这些化合物表现出良好的比例行为。
Nuclear and high energy physics research has a need for new, high performance scintillators with high light yields, high densities, fast decay times, and radiation hardness. In this paper we present crystal growth and results from 16-mm diameter cerium (Ce)-doped Tl2LaCl5(TLC) and europium (Eu)-doped TlCa2Br5(TCB) as well as one-inch diameter cerium-doped Tl2GdBr5(TGB) and europium-doped TlSr2I5(TSI), each grown in a two-zone vertical furnace by the modified Bridgman method. Samples extracted and processed from the grown boule are characterized for their scintillation properties like energy resolution, light yield, decay time and non-proportionality. Energy resolution (FWHM) at 662 keV of 5.1%, 3.4%, 4.0%, and 3.3% are obtained for samples of TGB, TLC, TCB, and TSI, respectively. Ce-doped TGB and TLC have single decay time components of 26 ns and 48 ns, respectively, while Eu-doped TCB and TSI have long decay times with primary decay constants of 571 ns and 630 ns? These compounds exhibit good proportionality behavior when compared to NaI:Tl and BGO.
