我们提出了一种塑料闪烁体，与Carlit Holdings Co.合作开发，有限公司、其使用通过添加硬化剂在室温下固化的液体母体材料制造。新的闪烁体可以结合热不稳定的功能材料，如钆，以提高中子灵敏度。利用90 Sr β射线源对这种新型闪烁体的特性，特别是光产额和衰减长度进行了评价。基于与市售闪烁体（BC-408）的比较，在距离光电探测器表面18 cm处测量光输出为7%蒽。由于光衰减，该光输出取决于发光点和光电检测器之间的距离。Gd掺杂闪烁体的衰减长度为约50 cm。
We present a plastic scintillator, developed in collaboration with Carlit Holdings Co., Ltd., that is fabricated using a liquid parent material cured at room temperature by adding a hardener. The new scintillator can incorporate heat-labile functional materials such as gadolinium to enhance neutron sensitivity. The characteristics of the new scintillator, in particular the light yield and attenuation length, were evaluated using a90Srβ-ray source. The light yield was measured 7% Anthracene on the basis of a comparison with commercially available scintillator (BC-408) at a distance of 18 cm from the photodetector surface. This light yield is dependent on the distance between the luminous point and the photodetector because of light attenuation. The attenuation length of the Gd-doped scintillator was about 50 cm.
