摘要： The present invention relates to a photoexcitable storage phosphor which comprises at least one rare earth element in the trivalent +3 oxidation state and wherein upon irradiation by X- ray, ?-ray or UV radiation the trivalent +3 oxidation state is reduced to divalent +2 oxidation state. The present invention also relates to a dosimeter, radiation image storage panel comprising the phosphor of the present invention and in dosimetry applications for applications including scientific, medical and other imaging applications. The present invention also relates to a process for making a photoexcitable storage phosphor and a process for recording and reproducing an image.
