| 摘要: |
Magnetite (Fe3O4) nanoparticles were controllably synthesized by aerial oxidation FeIIEDTA solution
under different monowavelength light-emitting diode (LED) lamps irradiation at room temperature. The
results of the X-ray diffraction (XRD) spectra show the formation of magnetite nanoparticle further
confirmed by Fourier transform infrared spectroscope (FTIR) and the difference in crystallinity of
as-prepared samples. Fe3O4 particles are nearly spherical in shape based on transmission electron
microscopy (TEM). Average crystallite sizes of magnetite can be controlled by different irradiation light
wavelengths from XRD and TEM: 50.1, 41.2, and 20.3 nm for red, green, and blue light irradiation,
respectively. The magnetic properties of Fe3O4 samples were investigated. Saturation magnetization
values of magnetic nanoparticles were 70.1 (sample M-625), 65.3 (sample M-525), and 58.2 (sample
M-460) emu/g, respectively. |
