Radiation damage of CsI:Eu crystals
The problems of radiation damage and afterglow nature for CsI:Eu crystal are discussed. It was determined that the luminescence parameters depend on the X-ray irradiation conditions. Irradiation leads to emission suppression at doses less than 100 Gy when the induced absorption was not observed yet....

The problems of radiation damage and afterglow nature for CsI:Eu crystal are discussed. It was determined that the luminescence parameters depend on the X-ray irradiation conditions. Irradiation leads to emission suppression at doses less than 100 Gy when the induced absorption was not observed yet. Hole (VF⁻ and I₃⁻) and activator′ color centers formation lead to partial decrease of the intrinsic UV and the activator luminescence, but it is not the dominating process of the radiation-induced phenomenon. The reverse dependences of afterglow and Eu²⁺ luminescence on irradiation dose were detected. Radiation induced luminescence quenching is determined by a modification of the activator centers structure.
