Research Progress on LYSO:Ce Scintillation Crystals

Abstract

Abstract: Cerium-doped lutetium-yttrium oxyorthosilicate (LYSO:Ce) crystals show excellent scintillation properties, and has been widely used in the filed of nuclear medicine, high-energy physics and safety inspection. The crystal structure, luminescent mechanism, main problems in the crystal growth and the possible direction of development of LYSO:Ce scintillation crystals are reviewed in this paper. Furthermore, the common issues with corresponding solutions in the crystal growth of LYSO:Ce are summarized, and further the space occupation of Ce³⁺ ions and the relationship between Ce⁴⁺ ions and scintillation properties are discussed. In addition, the latest research results from our groups in LYSO:Ce crystal growth are displayed and the dimension of φ95.42 mm×200 mm of LYSO:Ce scintillation crystal was grown using medium frequency induction furnace.

Key words: LYSO:Ce, scintillation crystal, crystal structure, crystal growth, scintillation mechanism, oxygen vacancy
