首次采用熔体淬冷法成功制备了新型掺Eu3+的BaLuF5纳米晶透明氟氧化物微晶玻璃。X射线衍射谱分析表明，新析出的微晶玻璃是以BaGdF5为基础的立方BaLuF5微晶玻璃。在微晶玻璃中观察到的强烈红光发射归因于Eu3+离子在BaLuF5纳米晶中的浓缩。此外，明显的斯塔克分裂发射，低的强迫电偶极子5D0，→7F2跃迁，以及Eu3+离子较长的衰变寿命也证明了Eu3+离子在低声子能量的BaLuF5纳米晶中的分配。这种透明材料可能会在光子学中得到应用。
Novel Eu3+-doped transparent oxyfluoride glass-ceramics containing BaLuF5 nanocrystals were successfully fabricated by melt-quenching technique for the first time. Analyses of XRD patterns prove that the new precipitated glass-ceramics are crystallized in cubic BaLuF5 based on isostructural BaGdF5. Intense red emissions observed in glass ceramics are attributed to the enrichment of Eu3+ ions into BaLuF5 nanocrystals. Besides, obvious stark splitting emissions, low forced electric dipole 5D0→7F2 transition, and long decay lifetimes of Eu3+ ions also evidence the partition of Eu3+ ions into BaLuF5 nanocrystals with low phonon energy. Such transparent material may find applications in photonics.
