摘要
占主导地位的X射线探测器主要分为直接半导体型X射线探测器和间接闪烁体型X射线探测器。近年来,杂化X射线探测器通过结合半导体和闪烁体材料的优势而出现。作为活性层的混合半导体和闪烁体导致了不同的工作机制。两相之间电荷/能量转移可以避免闪烁体的余辉效应。并且闪烁体的存在也优化了半导体材料的性能。本文总结了杂化X射线探测器的机制、进展和协同效应,以突出杂化X射线探测器的优势。根据不同的工作机制和各自的特点,我们详细讨论了三种类型的杂化X射线探测器。最后,我们对杂化X射线探测器存在的局限性和未来的发展方向进行了展望。
Dominating X-ray detectors are mainly divided into direct semiconductor X-ray detectors and indirect scintillator X-ray detectors.In recent years,hybrid X-ray detectors have emerged by combing the advantages of semiconductors and scintillators.The mixed semiconductors and scintillators as active layers lead to different working mechanisms.The charge/energy transfer between the two phases avoids the afterglow effect of the scintillator.And the presence of scintillators also optimizes the properties of the semiconductor material.The review summarizes the mechanism,progress,and synergistic effect of hybrid X-ray detectors to highlight the advances of hybrid X-ray detectors.Three types of hybrid X-ray detectors are discussed in detail according to different working mechanisms and their respective characteristics.Finally,we present an outlook on hybrid X-ray detectors’limitations and the future development direction.
