Fast 5d-4f luminescence in Sr9RE(PO4)7 (RE = Sc, Lu) complex phosphates doped with Pr3+ ions
The paper studies 5d→4f transitions in Sr9RE(PO4)7 (RE = Sc, Lu) doped with Pr3+ under X-ray and ultraviolet (UV) excitation at various temperatures and with different Pr3+ ions content. In objects with Sc, 5d → 4f emission is negligible compared to 4f → 4f emission. When Sc is substituted with Lu, 5d → 4f transition emission yield is immense under excitation in both energy ranges, while emission related to 4f → 4f transitions is weak, especially under UV excitation. X-ray luminescence yield strongly depends on temperature; the effect is stronger for objects with Lu. Luminescence decay kinetics measured for Sr9Sc(PO4)7:Pr3+ have a fast (τ∼15 ns) component. Novel Pr3+-doped phosphors may be used as a promising material for fast efficient converters of ionizing radiation.The paper studies 5d→4f transitions in Sr9RE(PO4)7 (RE = Sc, Lu) doped with Pr3+ under X-ray and ultraviolet (UV) excitation at various temperatures and with different Pr3+ ions content.
