HF-free synthesis of K2SiF6 and BaSiF6 nanoparticles by thermal decomposition

K2SiF6 and BaSiF6 nanoparticles are synthesized for the first time by thermal decomposition of a mixture consisting of oleic acid and 1-octadecene using ammonium fluoride as fluorine source instead of highly toxic hydrofluoric acid. The structural and morphological properties of the as-obtained nanocrystals are investigated.
