Comparative Studies of Scintillation Properties of Tl-based Crystals

Tl-based crystalline scintillators, such as Tl2ZrCl6, TlMgCl3, TlCdCl3, TlSrCl3, and TlBaCl3, were synthesized by the Bridgeman method. The scintillation light yields of these materials were evaluated under Cs-137 gamma-ray irradiation. The relationship between the photoabsorption peak channel and gamma-ray energy was evaluated using various radioisotopes. Furthermore, the same relationship for energy resolution was also investigated.
