Abstract
Spectroscopic properties of newly developed mixed Lu-x(RE3+)(1-x)AP:Ce crys tals (RE3+) are presented. These properties are compared with those of pure YAP:Ce, GdAP:Ce and LuAP:Ce crystals and qualitative discussion of Ce3+ or Ce3+ defect-related centres in crystals is presented. A comparison of spec troscopic and scintillation properties of newly developed Lu-x(RE3+)(1-x)AP :Ce crystals show that the most promising crystal for scintillation applica tions seems to be Lu(0.3)Y(0.7)AP:Ce but from the point of view of stopping power and Z(eff), Lu(x)Gd(1-x)AP:Ce crystals would probably be better.
