Cerium-doped lutetium oxyorthosilicate Lu2SiO5:Ce crystal is a well-known scintillator with an excellent figure-of-merit. In this paper, air annealing was used to further improve its scintillation properties. The samples cut from Czochralski grown Lu2SiO5:Ce crystals were annealed in air atmosphere at 1400 C for 10 h. Based on the analysis of the difference in the crystal’s spectra (such as absorption, emission, and thermoluminescence) obtained before and after annealing, we investigate the nature of the observed effects.
