Abstract

A method for synthesis of single-crystalline nanowires of alkaline-earth metal fluoride nanowires was investigated. The purity and crystallinity of alkaline-earth metal fluoride samples were characterized using power X-ray diffraction. CaF₂ products were fabricated using polycarbonate membranes with pore sizes as small as 50 nm, consisting of straight nanowires with uniform, homogeneous size. The diameters of CaF₂ nanowires obtained were in the range of 50∓5 nm. High resolution transmission electron microscopy (HRTEM) analysis confirmed that the CaF₂ nano wire is single crystalline, without any obvious defects or dislocations. The slightly increased surface roughness of the nanowires compared to those of ABO₄ reflects local differenced in smoothness oinnerinnner surfaces of polycarbonate versus alumina membrane pores.
