Abstract
A halide material, such as scintillator crystals of LaBr:Ce and SrI:Eu, with a passivation surface layer is disclosed. The surface layer comprises one or more halides of lower water solubility than the scintillator crystal that the surface layer covers. A method for making such a material is also disclosed. In certain aspects of the disclosure, a passivation layer is formed on a surface of a halide material such as a scintillator crystal of LaBr:Ce of SrI:Eu by fluorinating the surface with a fluorinating agent, such as Ffor LaBr:Ce and HF for SrI:Eu.
