Abstract
A single crystal yttrium aluminum perovskite scintillator has a minimum thickness of at least 5 mm and a transmittance of at least 50% at a wavelength of 370 nm. A method for fabricating the yttrium aluminum perovskite scintillator includes acquiring a yttrium aluminum perovskite single crystal boule, annealing the yttrium aluminum perovskite single crystal boule in an oxygen containing environment to obtain a partially annealed crystal, and annealing the partially annealed crystal in an inert environment or a reducing environment to obtain the yttrium aluminum perovskite single crystal scintillator.

A method for making a scintillator comprising:
- forming a boule consisting essentially of single crystal yttrium aluminum perovskite (YAP) using the Czochralski process;
- and
- performing a first annealing of the single crystal YAP in an oxygen containing environment, and a second annealing of the single crystal YAP in an inert environment to make the scintillator.
