AbstractHigh efficiency medical scintillator Lu2SiO5: Ce was studied by Synchrotron Radiation VUV spectra. The results show that two excitation bands in the range 250-320nm of powder sample become very weak in comparison with those of single crystal sample. The difference of the excitation band assigned to band to band transition between the two samples indicates that there are different defects in these two samples. Under VUV excitation ( 185nm), the emission spectrum of the two samples are similar. The emission band in the range of 350-500nm corresponding to 5d --> 4f transitions of Ce3+. It can be decomposed to three sub-band which come from two types of Ce3+ luminescence centers. A new weak emission band was observed under VUV excitation. It possibly originates from the second type of Ce3+ luminescence centers or defect.
