The present invention relates to a microcolumnar zinc selenide (ZnSe)
scintillator and uses thereof, and methods of fabrication of
microcolumnar scintillators using sublimation-based deposition
techniques. In one embodiment, the present invention includes a
scintillator including a microcolumnar scintillator material including
zinc selenide (ZnSe) and a dopant. The microcolumnar scintillators of the
present invention provide improved light channeling and resolution
characteristics, thereby providing high spatial resolution, highly
efficient scintillators.
