title: [Microwave-assisted route to fibre-like ternary NaFeS2 nanoparticles and its XPS].
abstract: Ternary NaFeS2 nanoparticles were obtained in aqueous solution at room temperature via microwave-assisted route. The products were fibre-like with the diameter less than 10 nm, which were characterized with X-ray diffraction (XRD) pattern, transmission electron microscope (TEM) image, selected area electron diffraction (SAED) pattern and X-ray photoelectron spectroscope (XPS) pattern. The results indicated that the composition of fibre-like ternary nanoparticles are with atomic ratio of Na:Fe:S=1:1.1:1.9. The mechanism for the formation of fibre-like NaFeS2 nanoparticles is discussed.
