ABSTRACT:
An article, having particular use as a scintillator, includes a thin film of calcium sulfide on a substrate, such as alumina, quartz, sapphire, or most glasses. The material is first formed in bulk with cerium sulfide, cerium oxide, or cerium, and lithium fluoride. The material is applied by physical vapor deposition in a relatively thin film to the substrate, and then at least the luminescent material is subjected to a high temperature for a period of time to effect recrystallization and activation of the material, such that the material acquires luminescent characteristics.
