【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。更多还原

【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.更多还原
