“…As pulse shape discrimination for various ionizing radiations is contingent upon the interaction dynamics between ionizing radiation and the scintillating material, as well as the local defect structure and the nature of luminescence centers, these characteristics have been investigated in scintillators like GGAG:Ce and KCaI 3 :Eu . Due to the PSD characteristic of CsI:Tl, this scintillator has been deployed in the electron–positron colliders in the Large Hadron Collider (LHC) for discrimination between electromagnetic radiation and hadrons, construction of several 4π detector arrays with particle identification capabilities such as the Dwarfball/Dwarfwall, the Michigan State University Miniball, and the Microball that exploits the PSD ability of CsI:Tl. Furthermore, CsI:Tl has been employed for particle identification in the Belle II experiment, which aims to explore physics beyond the standard model .…”

Investigating the effect of codopants on the afterglow and pulse shape discrimination of Tl-doped CsI is very crucial for its successful applications in the fields of particle identification and medical imaging. The present work primarily focuses on the details of the electronic structure and luminescence properties of single crystals doped with CsI and codoped with Tl + , Sr 2+ , and Eu 2+ . Our results reveal that there is a remarkable acceleration in the scintillation decay of the γ radiation of CsI:Tl codoped with Eu 2+ and Sr 2+ ions. Further, the deep energy level traps as evidenced by electronic structure calculations as well as thermoluminescence studies are found to be responsible for the observed changes in pulse shape discrimination and suppression of afterglow.
