Characterization of Ce,Ca:LuAG ceramic scintillators fabricated from co-precipitated powders
Original language description
In this work, Ce:LuAG and Ce,Ca:LuAG ceramic scintillators were vacuum sintered from the powders synthesized by the co-precipitation method. Composition and thermal behavior of the precursor, spectral and scintillation characteristics of the ceramics were investigated in detail. After calcination at 900 ◦C, amorphous precursor was completely transformed into LuAG and nano-powder with particle size of about 40 nm was formed finally. Light yield and relative intensity of the fast component of the Ce:LuAG ceramics are higher than those of Ce:LuAG ceramics prepared by the conventional solid-state reaction method. Furthermore, the scintillation decay of the Ce,Ca:LuAG ceramics is accelerated compared to the Ce:LuAG, with the LY(0.5 μs)/LY(3 μs) ratio of 93%.
