چکیده
To unambiguously clarify the long-debated crystal structure of low-temperature orthoborate ?-YBO3, single-crystals europium-doped ?-YBO3:Eu3+ were prepared via a high-pressure/high-temperature route at 7.5 GPa and 1400 °C. The was solved refined in monoclinic space group C2/c (no. 15) pseudowollastonite type, with lattice parameters a=11.3407(5), b=6.5501(3), c=9.5798(4) Å, ?=113.08(2)°. This determination corroborated by powder X-ray diffraction vibrational spectroscopy. 11B as well 89Y MAS NMR spectroscopy used to verify that our results are also accurate for undoped ?-YBO3 samples varying europium content under ambient pressure conditions. Additionally, luminescence properties Eu3+ doped ?-orthoborate determined comparison these ambient-pressure samples.
