Abstract The chase of perfect solvents used in liquid scintillation cocktails practically resulted in the existence of two groups based on representatives of linear alkylbenzene group and a group of naphthalene derivatives. The objectives of this paper were to evaluate spectral and main detection parameters, including the pulse shape discrimination suitability, of Diethyl-, Propyl-, and Dodecylbenzene as representatives of linear alkyl benzene derivatives (LAB) and Di-iso-propyl-, and 1-methylnaphthalene in connection with the new luminophore with high Stokes shift - 1-Phenyl-3-(2,4,6-trimethyl-phenyl)-2-pyrazoline. LAB solvents exhibited similar detection efficiencies reaching up to 100% for high energy beta and alpha particles, but at the same time showed slightly worse detection efficiency for H-3. It was demonstrated that the representatives of the group of naphthalene derivatives exhibited superior pulse shape discrimination ability over the LAB representatives.

适用于液体闪烁混合物的选定直链烷基苯和萘溶剂的比较

摘要 液体闪烁混合物中对完美溶剂的追逐实际上导致了以直链烷基苯为代表的两个基团和一组萘衍生物的存在。本文的目的是评估作为线性烷基苯衍生物 (LAB) 和二异丙基苯的代表的二乙基苯、丙基苯和十二烷基苯的光谱和主要检测参数，包括脉冲形状辨别适用性，以及 1 -甲基萘与具有高斯托克斯位移的新型发光体 - 1-苯基-3-(2,4,6-三甲基-苯基)-2-吡唑啉有关。LAB 溶剂对高能 β 和 α 粒子表现出相似的检测效率，高达 100%，但同时对 H-3 的检测效率略差。
