ABSTRACT:
A method for enhancing the light yield of a doped scintillation crystal may include a reducing step if the crystal includes a dopant, such as cerium in a first oxidation state, such as the 4+ state. The scintillation crystal may include a rare earth silicate. The reducing may include heating in an oxygen-free ambient. The reducing may be used after an oxygen vacancy filling step that causes at least some of the dopant to increase in its oxidation state.
