Preparation and Properties of Indium Compounds Doped Plastic Scintillators
摘要
Abstract
Plastic scintillators have been extensively used in the field of radiation detection due to their low cost,good environmental stability,and simple large-scale preparation.Common plastic scintillators generally have insuffi-cient detection efficiency due to their low effective atomic number,which limits their further application in high ener-gy radiation and other fields.There are various methods to introduce materials with high effective atomic number into plastic scintillators.Among them,organic heavy metal compounds,due to their partial properties as organic com-pounds,can dissolve in polymer matrices,providing a more effective way for plastic scintillators to improve radiation stopping power and detection efficiency.In this work,tris(2,4-pentanedionato)indium(Ⅲ)(In(acac)3)was select-ed as a dopant,plastic scintillators doped with different concentrations of In(acac)3 were successfully prepared for the first time,and the changes in optical and scintillation properties of plastic scintillators with different doping con-centrations were systematically studied.As the doping concentration increases,the effective atomic number and ab-sorption coefficient of the plastic scintillator gradually increase,while the light yield progressively decreases.Among them,mass fraction 3%In(acac)3 doped plastic scintillator achieves an optimal balance between light yield and de-tection efficiency,resulting in an enhanced gamma count rate.关键词
