Scintillation Properties of (Lu,Y)AlO3 Doped with Nd

(Lu,Y)AlO3 crystals doped with different concentrations of Nd were synthesized by the floating-zone (FZ) method to evaluate their scintillation properties, particularly in the nearinfrared (NIR) range. Under X-ray irradiation, scintillation due to the 4F3/2→4I11/2 transition of Nd3+ was observed at...

Zusammenfassung:(Lu,Y)AlO3 crystals doped with different concentrations of Nd were synthesized by the floating-zone (FZ) method to evaluate their scintillation properties, particularly in the nearinfrared (NIR) range. Under X-ray irradiation, scintillation due to the 4F3/2→4I11/2 transition of Nd3+ was observed at 1064 nm. The scintillation decay time profile was approximated by an exponential decay function, and the obtained value varied from 2–3 to 150 μs depending on the concentration of Nd3+.
