Abstract
A method for enhancing the light yield of a single crystal of cerium doped lutetium yttrium orthosilicate (LYSO) in response to irradiation with high energy radiation includes diffusing oxygen into the crystal by heating the crystal for a period of time in an ambient containing oxygen. This process of thermal oxygenation of the crystal effectively supplies oxygen to fill at least some of the oxygen vacancies in the body of monocrystalline LYSO. A scintillation detector comprises a monocrystalline body of LYSO enhanced by oxygen diffusion into the crystal.
