Abstract
- In this paper we report on the crystal growth, density functional theory (DFT) calculations and scintillation properties of Tl 3 LnCl 6 :Ce 3 + and TlLn 2 Cl 7 :Ce 3 + (Ln = Y, Gd). Crystals were grown by the Vertical Bridgman technique up to 16 mm in diameter and 25 mm long. Crystals of Tl 3 YCl 6 :Ce 3 + and Tl 3 GdCl 6 :Ce 3 + belong to the family of the Nesohalides which have the monoclinic crystal structure. Crystals of TlY 2 Cl 7 :Ce 3 + and TlGd 2 Cl 7 :Ce 3 + belong to the family of the Phyllohalides which have either the monoclinic or the orthorhombic crystal structure. The light yields of these Nesohalides and Phyllohalides are typically on the order of 35,000–40,000 ph/MeV. [ABSTRACT FROM AUTHOR]
