European Patent Office,
European patent number EP 1 553 430 A1, 13.07.2005                 

Abstract: The invention pertains to a scintillating material of the generic formula CsALiLn_(1-x)X₆: xCe³⁺, where X is either Br or I, A is Cs or Rb, Ln is Y or Gd or Lu and x is above 0.0005, generally under the form of monocristal. This material has a remarkably low decay time. It can be used to detect and/or discriminate neutron and/or gamma ray radiations.
