Abstract :
In this paper we present results of light yield, light pulse shape and low-temperature thermoluminescence (ltTL) measurements of Lu0.8Y0.2AlO3:Ce (0.4 and 0.55%) crystals. The light output was measured as between 1510±50 and 2190±70 phe/MeV and energy resolution at 662 keV ranged over 10–21% FWHM. Light pulse shapes consisted of two decay components, 20.0±1 ns (65%) and about 160 ns (35%). Performed ltTL measurements revealed three major peaks at 109, 160 and 195 K. A correlation between 109 and 160 K peaks and low light yield was observed.
