摘要

采用浮区法生长了掺入不同浓度Eu（0.5、1.0、5.0、10.0、15.0%）的镥铝石榴石单晶，研究了其光学和闪烁特性。在580 ~ 710 nm的光致发光（PL）和闪烁光谱中观察到Eu3+离子4f-4f跃迁引起的几个尖峰，估计PL和闪烁衰减时间为2.9 ~ 3.8 ms。我们用慢衰减装置测量了137Cs （662 keV）在γ射线照射下的脉冲高度光谱，并估计了样品的产光量。在所有样品中，掺入5.0%铕的镥铝石榴石样品的产光率最高，达到30000光子/MeV。

Scintillation properties of Eu3+ doped Lu3Al5O12 single crystals

Lutetium aluminum garnet single crystals doped with different concentrations of Eu (0.5, 1.0, 5.0, 10.0, 15.0 %) were grown using the floating zone method, and their optical and scintillation properties were investigated. Several sharp peaks due to 4f-4f transitions of Eu³⁺ ions were observed at 580–710 nm in photoluminescence (PL) and scintillation spectra, and the PL and scintillation decay times were estimated to be 2.9–3.8 ms. We measured the pulse height spectra under γ-ray irradiation from ¹³⁷Cs (662 keV) using the setup for scintillators with slow decay times, and the light yields of the samples were estimated. The 5.0 % Eu-doped lutetium aluminum garnet sample showed the highest light yield of 30,000 photons/MeV among the samples.
