摘要:

研究了有机胺和羧酸对LAB闪烁体发光的猝灭作用。猝灭剂的化学官能团在这种还原中起重要作用。结果表明,在混合胺-酸体系中以1:1摩尔比形成的“盐”使淬灭减少2倍。支持NMR光谱。这种“猝灭中和”有可能减少当与猝灭剂络合的金属被装载到有机光催化剂中时所引起的光损失。

英文摘要:

Quenching of light emission from an LAB based scintillator by the addition of organic amines and carboxylic acids is examined. Chemical functional groups of the quenching agents play an important role in this reduction. It is shown that "salt" formation at a 1:1 mole ratio in a mixed amine-acid system, reduces quenching by a factor of 2. Supporting NMR spectra are presented. This "quenching neutralization" has the potential to reduce the light loss incurred when metals complexed with quenching agents are loaded into organic scintillators.
