Abstract: We demonstrate a general single-pot heating method for preparing iron-doped zinc oxide nanocrystals from acetyl acetonate precursors in non-aqueous solvents. The particles were characterised by transmission electron microscopy (TEM), powder X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), UV-visible (UV-Vis) and Fourier transform infrared (FTIR) optical absorbance spectroscopies. The dependences of the size of the nanocrystals and doping level on the synthesis temperature and precursor composition were elucidated and modelled.

Keywords: crystal structure; nanostructures; semiconductors; chemical synthesis; X-ray diffraction; iron doping; zinc oxide; ZnO nanoparticles; single-pot heating; precursor composition; temperature; nanotechnology; nanocrystals; acetyl acetonate precursors; modelling.
