| Abstract: BaF2 nanoparticles were synthesized via a mild sonochemical route from an aqueous solution of Ba(NO3)2 and NH4F in the presence of complexing agent EDTA under ambient air. XRD, TEM and SEM were used to characterize the structure and shape of the product. The as-prepared BaF2 nanocrystals crystallize in a cubic structure and have an average crystal size of 10 nm. The amount of EDTA plays an important role in controlling the shape and size of the product. Comparative experiments using CTAB as surfactant instead of complexing agent EDTA showed cubic-shaped product with diameter of 400~500 nm. | |
