FeSi nanoparticles were synthesized via thermal decomposition of iron pentacarbonyl in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. The TEM images showed that FeSi nanoparticles had cubic shape, but it seemed that the composition was not uniform. According to the EDS results, the Fe:Si ratio of gray-uniform nanopaiticles was almost 1:1, and blacker FeSi nanoparticles contained more Fe atoms. Although FeSi didn't have uniform structure, it still could be proved that the incorporation of Fe and Si existed in a single nanoparticle. All possible structure, lattice, binding, morphology, surface condition would be discussed. These results indicated that perhaps FeSi2 was the main structure of the new products; however, due to incompletely combination and less synthesized time, it might still contain some part of Si and Fe structure. Besides, FeSi nanoparticles preserved the optical properties from Si atoms, but the PL intensity was much lower. The maxima PL peak appeared at 388 nm with the excitation at 300 nm. Their saturation magnetization, remanent magnetization and coercivity were measured by the SQUID, exhibiting their nearly superparamagnetic behavior.
