Abstract: Facile synthesizing ultrasmall nanoparticles at room temperature can promote the large-scale applications of nanotechnology. However, successful cases are barely reported, because ultrasmall nanoparticles usually need high temperature for nucleation and ligands for reducing the surface energy. Herein, we took cubic BiF3 as an example to synthesize ultrasmall Fe3+-doped BiF3 nanoparticles at room temperature. For only one minute, Smaller Fe3+ ions can successfully substitute for bigger Bi3+ ions in the BiF3 lattice. With increasing the Fe3+ doping content, the particle size of BiF3:Fe3+ nanoparticles decrease continuously. Amazing, ultrasmall Fe3+-doped BiF3 nanoparticles about 6.9 nm in size can be obtained when the Fe3+ doping content reaches 0.119. Moreover, the doping of Fe3+ ions gives rise to a remarkable changes in the band structure of BiF3:Fe3+-x samples. The ultrasmall Fe3+-doped BiF3 nanoparticles reported here may find potential applications in photocatalyst and fluorescent material.
