“…Based on these important properties, it can be used in the elds of high energy physics, 1-4 optical, 5,6 lasers, [7][8][9] and semiconductor buffer layer materials. 10,11 Nanoscaled barium uoride has higher F À conductivity than single crystal or polycrystalline uoride about 1 to 2 orders of magnitude, which has a great potential in the eld of ion conductors. [12][13][14] In addition, it also possesses novel electronic, magnetic, optical, chemical, and mechanical properties that cannot be obtained from its bulky counterparts.…”
