摘要

We report the size control of nickel nanoparticles (NiNPs) through thermolytic reduction. The NiNP size was found to be varying from mono to bimodal distribution as a function of the reaction temperature and time with a narrow size distribution of 2 to 20 nm. The NiNP size and shape have been followed by employing two different lipophilic alkaylamine ligands either hexadecylamine or oleylamine. X-ray diffraction analysis reveals that the NiNPs were crystalline FCC structure. Transmission electron microscopy (TEM) was used to characterize the NiNPs.
