Radiation Damage and Afterglow of Europium Doped Bi_4Ge_3O_(12)(BGO) Crystal

Xie Youyu Wei Zhongying Yin Zhiwen (Shanghai Institute of Ceramics,Academia Sinica)  
The radiation damage and afterglow of a series of Eu-doped BGO crystals werestudied by means of optical transmission spectra,fluorescence emission spectra andfluorescence pulse response analyses。Experimental results showed that a doping of5 ppm of Eu_2O_3(wt)in BGO crystal is enough to achieve the optimum conditionof radiation hardness and only a very small amplitude of afterglow appeared due toits low Eu~(3+) ion concentration.The mechanism of the improvement of the radiationhardness and the appearance of afterglow by doping small amount of Eu_2O_3 inBGO crystals were also discussed in the present paper.
