Influence of lutetium content on the scintillation properties in (LuxY1-x.)AlO3:Ce single crystals

Popis výsledku v původním jazyce

The absorption, luminescence, and scintillation characteristics of LuxY1-xAlO3:Ce single crystals were investigated. The values of light yield, scintillation decay time, and coincidence time resolution were evaluated. The light yield obtained for YAlO3:Ce is much higher than that for Lu0.3Y0.7AlO3:Ce and Lu0.7Y0.3AlO3:Ce. The decays are dominated by a fast component of 16?20 ns, which nearly coincides with the photoluminescence decay time 17.5 ns. In scintillation decays the intensity of the fast component becomes reduced and the content of slower components considerably increased with increasing lutetium content. The coincidence time spectra for 511 keV annihilation quanta were measured in coincidence experiment using a BaF2-based detector and time resolution was also discussed. The photofraction for all the samples was also evaluated and discussed.
