The purpose of this work is to understand, for Ce doped materials, how the effect of the local crystal environment of Ce compared to the character of the host cation, influences the scintillation and fluorescence of different materials. In the case of YAP (YAlO3) and LAP (LaAlO3) while very similar materials, YAP is a moderately bright Ce activated scintillator while LAP shows no Ce activation. It...
We developed Lu0.4Gd1.6SiO5 (LGSO) crystal as a new scintillator for medical applications. Physical and scintillation properties of LGSO crystals with various Ce concentrations and annealing effect were studied. Its absorption coefficient at 511 keV gamma ray is 0.70 cm-1 which is the same as GSO. Annealed crystal with 2.0 mol% of Ce shows better scintillation properties such as high light output...
