Near-infrared scintillation phenomenon in Nd<sup>3+</sup>-activated BaO-PbO-P<sub>2</sub>O<sub>5</sub> glasses and glass-ceramics
Abstract BaO-PbO-P 2 O 5 glasses and glass-ceramics activated by Nd 3+ were successfully synthesized by the melt-quenching technique. Nd was doped at molar ratios of 0, 1, 5, 10, and 15%. Glass samples were obtained by 0%–5% Nd-doping, and glass-ceramic samples were obtained by 10 and 15% Nd-doping. Glass-ceramic samples contained monazite NdPO 4 crystalline phases. Nd-doped samples exhibited photoluminescence and scintillation in the near-infrared region, originating from 4f–4f transitions of Nd 3+ . The lower detection limit of X-ray dose rates was 11 mGy h −1 .
