[Bis(acetylacetonato)zinc(II)] was used as a precursor to prepare zinc oxide nanoparticles of 12–20 nm in average diameter by thermal decomposition. The different combinations of triphenylphosphine, (C
18H
15P) and oleylamine, (C
18H
37N) were added as surfactants to control the particle size. The products were characterized by X-ray diffraction (XRD), photoluminescence spectroscopy (PL), FT-IR spectroscopy, surface area, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to depict the phase and morphology. The synthesized ZnO nanoparticles have a hexagonal zincite structure. The photoluminescence of ZnO nanoparticles was studied by exciting the sample with an ArF laser (193 nm). A strong blue-shift of the emission band of ZnO, suggesting a strong quantum size effect, is observed.
