High melting temperature Nd-doped Lu₂O₃ single crystals (ρ = 9.4 g/cm³) showing near-infrared emission have demonstrated a favorable signal-to-noise ratio even under high-dose-rate condition ( ~1 kGy/h). In this study, to further enhance these advantageous properties, Lu₂O₃ single crystals with identical host composition were grown with various Nd concentrations, and detailed characterization was conducted to elucidate the factors contributing to the enhancement of near-infrared emission intensity.
