X-ray radiation excited ultralong (>20,000 seconds) intrinsic phosphorescence in aluminum nitride single-crystal scintillators

Abstract

Phosphorescence emission from extrinsic rare-earth element and organic component remains a challenge. Here, the authors demonstrate an ultraviolet ultralong intrinsic phosphorescence (UIP, >20,000 seconds) in aluminum nitride (AlN) single-crystal scintillator through X-ray excitation.
