Abstract

Metal β-diketonates and carboxylates have been studied with the aim to use them in element-containing liquid organic scintillators. Their effect on the light yield and transparency of scintillators has been studied. Absorption spectra of neodymium and zirconium β-diketonates and neodymium and gadolinium 3,5,5-trimethylhexanoates have been reported. In terms of specific light yield of scintillators with added β-diketonates and carboxylates, it has been concluded that the high values of specific light yield at large concentrations of β-diketonates (50%) can be achieved only on addition of considerable amounts of scintillation additives (up to 100 g/L). The stability of metal-containing scintillators related to the structure of added compounds, purity of all components of scintillator, and effect of metal carboxylates and β-diketonates on alkylbenzene oxidation have been studied.

用于设计含元素液体有机闪烁体的金属（Gd、In、Nd、Zr）β-二酮酸盐和羧酸盐

摘要

已经研究了金属 β-二酮酸盐和羧酸盐，目的是将它们用于含元素的液体有机闪烁体。已经研究了它们对闪烁体的光输出和透明度的影响。已经报道了钕和锆 β-二酮酸盐以及钕和钆 3,5,5-三甲基己酸盐的吸收光谱。就添加了 β-二酮酸盐和羧酸盐的闪烁体的比光产率而言，得出的结论是，只有添加大量的闪烁体才能在高浓度 β-二酮酸盐 (50%) 下实现高值的比光产率添加剂（高达 100 克/升）。含金属闪烁体的稳定性与添加化合物的结构、闪烁体各成分的纯度、
