摘要: 室温下快速合成了Fe3+掺杂的BiF3超小纳米粒子,只需要反应1 min,较小的Fe3+离子即可替代BiF3晶格中较大的Bi3+离子.随着Fe3+掺杂量的增加,BiF3:Fe3+纳米粒子的粒径不断减小,当Fe3+的掺杂量达到0.119时,可以得到尺寸约为6.9 nm的Fe3+掺杂BiF3超小纳米粒子.此外,Fe3+离子的掺杂使BiF3:Fe3+-x样品的能带结构发生了显著变化.制备的Fe3+掺杂BiF3超小纳米粒子在光催化剂和荧光材料方面具有潜在的应用价值.

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.
