Abstract

The effect of higher Ce-concentration on the luminescence and scintillation properties of Cs₂LiGdBr₆ single crystals are studied. We used the Bridgman method for the growth of Ce-doped Cs₂LiGdBr₆ single crystals. Luminescence properties of the grown crystals are measured by X-ray and proton excitations. We measured the pulse height and fluorescence decay time spectra of Cs₂LiGdBr₆:Ce³⁺ with a bi-alkali photo multiplier tube (PMT) under γ-ray excitation from ¹³⁷Cs source. Improvements in the scintillation properties are observed with the increase of Ce-concentration in the lattice. Detailed procedure of the crystal growth is also discussed.
