摘要
A sample of Eu3+-activated lutetium sesquioxide transparent ceramic has been investigated by combined scintillation and thermoluminescence excited by prolonged gamma-ray irradiation. The thermoluminescence glow curve partially confirms and extends a previous model for afterglow following pulsed X-ray excitation. The initial concentration of hole traps, tentatively attributed to anion Frenkel defects in thermodynamic equilibrium, is found to be substantially augmented by reversible radiation damage.
