Abstract

The detailed scintillation response and properties of newly developed GYAP:Ce single crystals were studied using γ-ray quanta in the 8–1300 keV energy range (light yield, energy resolution, nonproportionality and scintillation decay). The scintillating properties of these multicomponent GYAP:Ce crystals were compared with those of the latest grown YAP:Ce crystals. In general, GYAP:Ce crystals exhibit a higher light yield of up to 30000 ph/MeV against 23000 ph/MeV for YAP:Ce reference crystal. The energy resolution of YAP:Ce is ≈ 4–5% for 662 keV energy of ¹³⁷Cs source, while for GYAP:Ce crystals values between 5 and 9 % were observed. The non-proportionality of GYAP:Ce crystals reach ∼70-80% at an energy of 10 keV while that of YAP:Ce reaches ∼85 %. 1/e scintillating decay times of GYAP:Ce crystals are between 60 and 100 ns which is almost twice higher than ≈48.8 ns 1/e decay time of YAP:Ce reference crystal. Another difference between GYAP:Ce multicomponent and YAP:Ce crystals is a presence of slow decay components in GYAP:Ce compared with YAP:Ce due to energy transfer processes between Ce³⁺ impurity and Gd³⁺ sublattice ions.

GYAP:Ce多组分钙钛矿新进展

利用8-1300 keV能量范围内的γ射线量子（光产率、能量分辨率、非比例性和闪烁衰减）研究了新开发的GYAP:Ce单晶的详细闪烁响应和性质。将这些多组分YAP:Ce晶体的闪烁性能与最新生长的YAP:Ce晶体进行了比较。总的来说，YAP:Ce晶体的产光率高达30000 ph/MeV，而YAP:Ce参考晶体的产光率为23000 ph/MeV。137Cs源能量为662 keV时，YAP:Ce的能量分辨率为 ≈ 4-5%，而GYAP:Ce晶体的能量分辨率为5 - 9%。在能量为10 keV时，YAP:Ce晶体的非比例性达到~ 70-80%，而YAP:Ce晶体的非比例性达到~ 85%。YAP:Ce晶体的1/e闪烁衰减时间在60 ~ 100 ns之间，几乎比YAP:Ce参考晶体的1/e衰减时间≈48.8 ns高2倍。GYAP:Ce多组分和YAP:Ce晶体的另一个区别是，由于Ce3+杂质和Gd3+亚晶格离子之间的能量转移过程，与YAP:Ce相比，GYAP:Ce中存在慢衰减成分。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
