J. Phys.: Condens. Matter 14, 8481-8496 (2002)                 

Abstract: The optical and scintillation properties of pure and Ce³⁺-doped Cs₂LiYX₆ (X = Cl, Br) are presented. X-ray-excited optical luminescence spectra, optical excitation and emission spectra, time-resolved excitation and emission spectra, scintillation pulse height spectra and scintillation decay time spectra of Ce³⁺-doped Cs₂LiYX₆ (X = Cl, Br) crystals measured from 10 to 300 K are presented. Factors influencing the scintillation mechanism and the presence of core-valence luminescence are discussed.
