English term or phrase: scintillator
Definition from European Nuclear Society:
Substance in which flashes of light are generated by impinging ionizing radiation (fluorescence). Nal(Tl)-monocrystals are particularly suitable for the detection of gamma radiation and anthracene or diphenyl oxazole dissolved in toluene is suitable for beta radiation. ZnS(Ag) is a favourable scintillator for detection of alpha radiation.

Example sentence(s):
  • Gadolinium silicate doped with cerium is a "fast" crystal and can be used as a protection scintillator. Its possible applications include computer tomography, spatial resolution of less than 1 mm. Marketech International
  • YAG (Yttrium Aluminum Garnet) single crystal scintillators are chosen by many scanning electron microscopists because they have a very fast response time of 50 - 60ns and (unlike plastic or most phosphor scintillators) they do not degrade when bombarded by electrons or ions. Canemco & Marivac
  • Plastic scintillators are prepared by bulk polymerization in aluminium (size up to 3.5 m) or glass cast and by pressure molding technique. Amcrys-H

閃爍體


Definition from 辐射小常识 (湖南省环境保护:
闪烁体是一类能吸收能量,并能在大约一微秒或更短的时间内把所吸收的一部分能量以光的形式再发射出来的物质。闪烁体分为无机闪烁体和有机闪烁体两大类,闪烁体必需具备的性能是:对自身发射的光子应是高度透明的。闪烁体吸收它自己发射的一部分光子所占的比例随闪烁材料而变化。无机闪烁体[如Nal(Tl),ZnS(Ag)]几乎是100%透明的,有机闪烁体(如蒽,塑料闪烁体,液体闪烁体)一般来说透明性较差…

Example sentence(s):
  • 闪烁探测器(scintillation detector)主要由闪烁体、光的收集部件和光电转换器件组成的辐射探测器。当粒子进入闪烁体时,闪烁体的原子或分子受激而产生荧光。利用光导和反射体等光的收集部件使荧光尽量多地射到光电转换器件的光敏层上并打出光电子。 - 中国百科网--物理百科知识  
  • 飛行時間計數器 (Time-of-flight Counters) 這是由反應非常快的閃爍體 (Scintillator) 所構成的偵測器, 磁鐵之上有二層﹑之下有二層。 當帶電粒子穿過閃爍體時, 會激發閃爍體的原子而使其放出光來。 藉由測量光在這四層閃爍體出現的時間, 可以推算帶電粒子從第一層飛到第四層的飛行時間, 進一步可以求得帶電粒子的速度。 - 中央研究院

  -> thank you :)

neutral  ysun: 閃爍體 is just a synonym of 闪烁剂. Both 閃爍劑 and 閃爍體 are used in Taiwan and mainland China. In fact, 閃爍劑 is the official translated term in Taiwan.

闪烁剂


Definition from 化工词典:
闪烁剂是通过记录其辐射发光来测量放射性的一类物质。它们是一些具有高荧光量子效率、短荧光寿命和良好溶解性能的化合物(发色体)。通常将其溶于芳香族液体和高聚物中,分别制成有机液体闪烁剂和塑料闪烁体。

Example sentence(s):
  • 《新型闪烁剂PMP用于α辐射核素的测量》 Use of a novel scintiflator PMP for counting α-emitters - 《核技术》1988年06期  
  • 本研究以合成方式將奈米級二氧化鈦及無機閃爍劑微粒燒結於陶瓷粉末上,形成可以利用輻射能之輻射敏感型光催化劑,利用其中的無機閃爍劑作為吸收輻射能,並轉換為可以激發二氧化鈦之敏感劑。 This paper describes the synthesis of radio-sensitive photocatalyst (BaF2/TiO2/ceramic) in which the co-existence of nano-phase titania and scintillator on the ceramic powder. - Taiwan Electronic Periodical Services

闪烁体 is just a synonym of 闪烁剂 (English-Chinese Dictionary of Chemistry and Chmical Engineering, 4th edition). 閃爍劑 is also use in Taiwan. Actually, the National Institute for Compilation and Translation in Taiwan (国立编译馆), which is a government agency in Taiwan http://www.nict.gov.tw/, made it official.
