3-(p-Toluidino)-5-phenyl-1-p-tolyl-1H-pyrrol-2(5H)-one as an organic liquid scintillator used for gamma spectroscopy

In this article, the scintillation properties of 3-(p-toluidino)-5-phenyl-1-p-tolyl-1H-pyrrol-2(5H)-one as a Lactam is studied. m-xylene, cyclohexan, and ethanol are used as solutions, whilst, Anteracene and Naphthalene are used as secondary solvents. The influence of solvent on the scintillation efficiency is studied. The results show that the proposed material can be used as an organic scintillator but its efficiency for gamma spectroscopy is relatively low (～5% of NE213 of similar size).
