塑料闪烁体(以下简称塑闪)是广泛应用的闪烁探测器的一种。 我们在最近两年内研制成功了ST1421,ST1422,ST1423和ST1431等四种新型塑料闪烁体。它们是ST401型的基础上衍生出来的,达到了国外同类型产品70年代末期的水平。它们的基质材料都采用国外广泛采用的乙烯基甲苯,发光材料和其他添加剂的种类和含量进行了筛选和对比,采用最佳方案。制备方法采用本体热聚合法。 Plastic scintillator (hereinafter referred to as plastic flash) is a widely used scintillation detector. We have successfully developed four new plastic scintillators such as ST1421, ST1422, ST1423 and ST1431 in the last two years. They are based on the ST401 model derived from the same type of product reached the level of the late 70s. Their matrix materials are widely used abroad, vinyl toluene, luminescent materials and other additives of the type and content of the screening and comparison, using the best solution. Preparation method using bulk thermal polymerization method.
