| description | The Nd-doped LaMgAl<sub>11</sub>O<sub>19</sub> 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<sup>3+</sup> were observed at 900, 1060, and 1340 nm in the near-infrared range, and the decay curves show the typical decay time for Nd<sup>3+</sup>. The samples show good afterglow properties comparable with practical X-ray scintillators. The 1% and 3% Nd-doped LaMgAl<sub>11</sub>O<sub>19</sub> samples show a good linearity in the dynamic range from 6–60,000 mGy/h. |
