Abstract

Optical absorption measurements before and after X-ray irradiation (induced absorption) were performed in order to investigate the radiation damage of the Eu³⁺-doped Bi₄Ge₃O₁₂ (BGO) crystals. The Eu³⁺-doped BGO has shown higher radiation resistance with respect to the equivalently grown undoped BGO crystals. Radio-, photo- and thermo-luminescence characteristics were obtained to clarify the role of Eu³⁺ in luminescence and scintillation mechanism in Eu ³⁺-doped BGO. Also, the role of Eu³⁺ in the processes of energy transfer and storage in this material could be explained.
