发明名称 Passivation of Metal Halide Scintillators
摘要 A halide material, such as scintillator crystals of LaBr3:Ce and SrI2: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 LaBr3:Ce of SrI2:Eu by fluorinating the surface with a fluorinating agent, such as F2 for LaBr3:Ce and HF for SrI2:Eu.

主权项 1. A material, comprising: a first metal halide that is operative to function as a scintillator; where the first metal halide excludes cesium iodide and cesium bromide; and a surface layer comprising a second metal halide that is disposed on a surface of the first metal halide; where the second metal halide has a lower water solubility than the first metal halide.
