摘　　要：High temperature (from room temperature to 773 K) thermoluminescence of BaFCl: Eu2+ is reported. Three new glow peaks have been found to be caused respectively by F2-, F3 - and F4- centers which are the aggregates of F centers. Physical parameters characterizing those peaks are present. It is pointed out that the thermoluminescence process in BaFCl:Eu2+ is very complex. Accompanying this process, there occur electron transfers among different centers and dissociation of the aggregates.High temperature (from room temperature to 773 K) thermoluminescence of BaFCl: Eu2+ is reported.
