Scintillation characteristics of lutetium oxyorthosilicate (Lu2SiO5:Ce) crystals doped with cerium ions

Cerium-doped lutetium oxyorthosilicate crystals with dimension of ∅40×60 mm3 were grown by Czochralski method from an inductively heated iridium crucible. The crystal structure was examined by XRD and confirmed to be monoclinic symmetry. Its optical transmission, UV-excited, X-ray excited emission and light yield were measured at room temperature. Its decay time was also tested under optical excitation and gamma excitation, respectively.
