Phase Relations and Solid Solutions in the YbBO3–ScBO3 System
The YbBO3–ScBO3 system was studied across the selected compositional range by means of solid-state synthesis, powder X-ray diffraction (XRD), differential scanning calorimetry (DSC), and photoluminescence spectroscopy. XRD of annealed samples at 1300–1400 °C revealed that the system reaches equilibrium and consists of two phases, YbBO3 and ScBO3, separated by a two-phase region. The lattice parameters show a limited solubility between Yb3+ and Sc3+ ions. DSC measurements display a broad endothermic feature at approximately 1480 °C, corresponding to the eutectic point. Near-infrared emission excited at 975–980 nm originates from Yb3+ ions and shows the highest intensity for pure YbBO3 and for the Sc-rich composition, while intermediate samples exhibit weaker luminescence.
