碱土金属氟化物由于具有化学惰性、低晶格声子能等优良性质，被广泛认为是无机发光材料和荧光粉的主体[1-3]。Mn 4+掺杂的六氟化钡BaXF 6（X = Si、Ge、Ti或Sn）可以潜在地用于商业LED中，以便将来自传统白色发光LED的UV-蓝色发射转换为红色发射，以减少在长时间暴露于UV蓝光之后可能出现的与健康相关的影响[4]。这些材料具有优异的光致发光特性，可用于多种应用，如彩色多路复用[5]，光学传感[6]和温度传感[7]。此外，当掺杂稀土离子时，这些材料表现出快速的衰减时间。在这项工作中，高的纵横比单晶BaXF 6纳米线合成的溶剂热法，并使用电子探针显微分析仪（EPMA）进行分析。
Alkaline earth fluorides are widely recognized as the hosts for the fabrication of inorganic scintillators and phosphors, due to favorable properties such as chemical inertness, low lattice phonon energy, etc. [1-3]. Mn 4+ -doped barium hexafluorometallates, BaXF6 (X = Si, Ge, Ti, or Sn) can be potentially used in commercial LEDs in order to convert the UV-blue emissions from the conventional white light emitting LEDs to red emissions to reduce the health-related impacts that may arise after prolonged exposure UVblue light [4]. These materials have excellent photoluminescence properties and can be useful for several applications such as color multiplexing [5], optical sensing [6], and temperature sensing [7]. Furthermore, when doped with rare-earth ions, these materials exhibit fast decay time. In this work, high aspect-ratio single-crystal BaXF6 nanowires were synthesized by a solvothermal method and are analyzed using an Electron Probe Microanalyzer (EPMA).
