Size-controlled synthesis and morphology evolution of bismuth trifluoride nanocrystals via a novel solvent extraction route

Monodisperse orthorhombic-phase BiF3 nanocrystals with various shapes were prepared easily by a novel solvent extraction approach using an acid-base-coupled extractant. More importantly, the extractant used in this route can be recycled after synthesis. Our results show great promise for further extending the method to the preparation of other metal-fluoride nanoparticles.
