| Abstract: | Pure zirconium oxide (ZrO2) nanocrystals with diameters 10-30 nm are fabricated from bis-aqua, tris-acetylacetonato zirconium(IV) nitrate; [Zr(acac)3(H2O)2](NO3); by thermal decomposition. The different combinations of oleylamine, or polyethyleneglycol (PEG) and triphenylphosphine, were added as surfactants to control the particle size. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis) spectroscopy, photoluminescence spectroscopy (PL), Fourier transform infrared (FT-IR) spectroscopy and X-ray photoelectron spectroscopy (XPS) to depict the phase and morphology. The synthesized ZrO2 nanoparticles have a cubic structure. The FT-IR spectrum showed the purity of obtained ZrO2 nanocrystals with cubic phase. The UV-Visible absorption peak for ZrO2 was observed at 233 nm (5.3 eV in photon energy). The band at 363 nm for cubic ZrO2 nanocrystals was found. |
