Scintillation Response of Nd-Doped LaMgAl(11)O(19) Single Crystals Emitting NIR Photons for High-Dose Monitoring

The Nd-doped LaMgAl(11)O(19) single crystals were synthesized by the floating zone method, and the photoluminescence and scintillation properties were evaluated. Under X-ray irradiation, several sharp emission peaks due to the 4f–4f transitions of Nd(3+) were observed at 900, 1060, and 1340 nm in th...

Sumario:The Nd-doped LaMgAl(11)O(19) single crystals were synthesized by the floating zone method, and the photoluminescence and scintillation properties were evaluated. Under X-ray irradiation, several sharp emission peaks due to the 4f–4f transitions of Nd(3+) were observed at 900, 1060, and 1340 nm in the near-infrared range, and the decay curves show the typical decay time for Nd(3+). The samples show good afterglow properties comparable with practical X-ray scintillators. The 1% and 3% Nd-doped LaMgAl(11)O(19) samples show a good linearity in the dynamic range from 6–60,000 mGy/h.
