摘要：

Cerium and molybdenum-activated lutetium. aluminum perovskite (LuAlO3, LuAP) and mixed lutetium-yttrium aluminum perovskite (LuxY1-xAlO3, LuYAP) scintillator crystals have been grown by the Czochralski method at the Institute of Electronic Materials Technology (ITME, Warsaw). In this paper we report the measurements of scintillation light yields, absorption spectra, scintillation time profiles, low temperature thermoluminescence, and room temperature afterglow, performed on polished 2 x 2 x 10 nun 3 pixel samples cut from larger boules. We show that scintillation properties of the LuAP:Ce and LuAP:Ce,Mo crystals from ITME place them among the best crystals produced commercially. (c) 2006 Elsevier B.V. All rights reserved.
