闪烁晶体 非氟卤化物 光输出 能量分辨率 研究与开发 scintillation crystal non-fluorinated halide light output energy resolution research and development
摘要
本文根据化学组成的特点将非氟卤化物闪烁晶体划分为AX、MX、RX3、AMX3、A2MX4、A4MX6、AM2X5、ARX4、A2RX5、A2A′RX6、A3RX6、A2TX6型等,其中A、M、R和T分别代表+1价、+2价、+3价和+4价的金属元素,X代表除氟以外的卤族元素,A′表示与A不同的+1价金属元素。着重介绍了其中光输出高于40 000 ph/MeV的γ射线探测用闪烁晶体以及光输出高于20 000 ph/MeV的中子和γ射线双探测用闪烁晶体,并对它们的研究现状和发展趋势进行了简要评述。
Abstract
The non-fluorinated halide scintillation crystals are divided into AX, MX, RX3, AMX3, A2MX4, A4MX6, AM2X5, ARX4, A2RX5, A2A′RX6, A3RX6, A2TX6 and so on according to the chemical composition characteristics, where A, M, R and T represent metal elements with the valence of +1, +2, +3 and +4, respectively; X for halogen elements except fluorine, and A′ for +1 valent metal element different from A. The non-fluorinated halide scintillation crystals with light output of more than 40 000 ph/MeV for γ-ray detection, and those of more than 20 000 ph/MeV for both thermal neutron and γ-ray detection are emphatically introduced, and their research status and development trend are briefly reviewed.
