摘要

在聚硅氧烷碱上制造抗辐射闪烁组合物的问题之一是寻找一种能够充分溶解在这种碱中的抗辐射活化剂。为了提高对terphenyl分子在聚硅氧烷碱中的溶解度，本文采用叔丁基取代基对其结构进行了修饰。得到的对三苯基的烷基衍生物被用作聚硅氧烷基闪烁体的活化剂。研究了所制备的聚硅氧烷基闪烁体的光学性能和闪烁性能，并测定了其辐射硬度。

Alkyl derivative of p-terphenyl as an activator of polysiloxane-based scintillator

One of the problems in creating a radiation-hard scintillation composition on a polysiloxane base is the search for a radiation-hard activator capable of dissolving in such a base in sufficient quantity. In this work, in order to improve the solubility of p-terphenyl molecules in a polysiloxane base, its structure was modified with tert-butyl substituents. The obtained alkyl derivative of p-terphenyl was used as an activator of polysiloxane-based scintillators. The optical and scintillation properties of the obtained polysiloxane-based scintillators were studied, and their radiation hardness was determined.
