1.0% Nd-doped BaCl2 transparent ceramic and single crystal samples were respectively prepared by spark plasma sintering and the vertical Bridgman–Stockbarger method to compare their optical and scintillation properties. The photoluminescence quantum yield of the crystal sample was 5.4% under 580 nm excitation, whereas that of the ceramic sample was below the detection limit of the device. In the scintillation spectra, multiple emission peaks derived from 4f–4f transitions of Nd3+ were observed in the 530–1330 nm range for both samples. For the dose rate response function, the lower detection limits of the ceramic and crystal samples were 0.03 and 0.003 Gy/h, respectively. Our samples had better detection limits than previously reported values of Nd:CsI (0.06 Gy/h) and Nd:CaWO4 (0.06 Gy/h) single crystals.
