Synthesis of BaFBr Nanoparticles from Microemusion

摘要：

BaFBr nanoparticles were synthesized by cetyltrimethylammonium bromide (CTAB)/2-octanol/water microemusion systems. X-ray diffraction (XRD) analysis shows that depending on the molar starting ratio of NH4F to NH4Br, stoichiometric BaFBr with or without a BaF2 phase is obtained. As the ratio of NH4F to NH4Br reduced from 1.0:1.0 to 1.0:4.0, the product forms pure BaFBr. Calculations using Debye-Scherrer equation from line widths of the XRD and images of transmission electron microscopy (TEM) show particle sizes of less than 100nm.
