The influence of Sc/Lu ratio on the phase transformation and luminescence of cerium-doped lutetium scandium orthoborate solid solutions

▶ Doping more than 10 at.% Sc3+ can stabilize calcite phase of LuBO3 up to 1550 °C. ▶ Luminescence properties of Lu1−xScxBO3:Ce solid solutions depend on the Sc/Lu ratio. ▶ Luminescence properties of Lu1−xScxBO3:Ce solid solutions depend on the Ce/RE ratio. ▶ Integrated intensity of (Lu0.5Sc0.5)0.995Ce0.005BO3 crystal can achieve 27% of LYSO:Ce crystal. ▶ Lu1−xScxBO3:Ce could be a potential scintillator in X-ray or γ-ray detection technology.
