摘要
Luminescence and scintillation properties of Cs2LiYCl6:Ce were further investigated. Core-valence (CV) luminescence characterized by an excitation band above 14 eV and a 2 ns fast and broad emission band was found. Light yields and decay times under gamma excitation were studied for various Ce concentrations. The 0.1% Ce-doped Cs2LiYCl6 was further examined under thermal neutron irradiation. It showed a very high light yield of 70500 photons/neutron. Furthermore the pulse shape for thermal neutrons is different from that for gamma-rays which gives the ability of neutron/gamma-pulse shape discrimination. (C) 2004 Elsevier B.V. All rights reserved.
