The physics and structure-property relationships of scintillator materials: effect of thermal history and chemistry on the light output of scintillating glasses
The scintillation light output of a series of silicate glasses has been determined for a fixed electron energy deposition. The glasses are cerium-doped lithium-aluminosilicates. Scintillation light output measurements were made as a function of lithium and alumina concentration and of annealing history. In this system, the cerium outer electron cloud serves as a sensitive probe of the local glass structure. From these measurements, a sensitivity matrix relating the light output to the structure is developed and presented. A conceptual model for the behavior of the light output is also presented.
