通过多元醇还原过量配体中的乙酰丙酮铂和乙酰丙酮铁，一锅法制备了粒径大于5 nm的FePt纳米颗粒。得到的大尺寸FePt纳米颗粒（6.1 +/- 0.6 nm Fe36Pt64、5.8 +/- 0.7 nm Fe44Pt56和5.1 +/- 0.7 nm Fe49Pt51）的热稳定性优于小尺寸FePt纳米颗粒，且其二维超晶格难以在平面方向上聚结。
One-pot synthesis of FePt nanoparticles larger than 5 nm with controlled composition has been developed by the polyol reduction of platinum acetylacetonate and iron acetylacetonate in excess ligands. The obtained large FePt nanoparticles (6.1 +/- 0.6 nm Fe36Pt64, 5.8 +/- 0.7 nm Fe44Pt56, and 5.1 +/- 0.7 nm Fe49Pt51 nanoparticles) were thermally more stable than the small ones and were hard to coalesce in the in-plane direction for their 2D superlattice.
