Nd³⁺ ions are promising emission centres for near-infrared emission scintillators, as they emit light at 1060 nm, which is located in the second optical window of living organisms. In this study, Nd-doped Mg₄Ta₂O₉ single crystals were prepared and their photoluminescence and scintillation properties were evaluated. In the X-ray-induced scintillation spectra in the near-infrared region, luminescence due to the 4f-4f transition of Nd_³⁺ was observed around 900 nm, 1060 nm and 1340 nm.
