Abstract
A scintillator can include an elpasolite scintillator compound. The scintillator can be doped with a Group 2 element, and may also include an activator. The scintillator has an improved core valence luminescence at room temperature as compared to a corresponding elpasolite scintillator compound without the Group 2 dopant. The elpasolite scintillator compound can have significant core valance luminescence at a temperature higher than 125° C. In a particular embodiment, the elpasolite scintillator compound can include Cl and may or may not also include another halide, such as Br or I. The scintillator can be part of an apparatus that detects gamma radiation and neutrons and may allow a relatively simpler pulse discrimination technique to be used to a higher temperature, such as 125° C. to 150° C. before a relatively more complex pulse discrimination technique would be used.
