چکیده | ||
The influence of the particle size on magnetic behaviors of nickel oxide nanoparticles (NiO NPs) was reported. NiO NPs with a uniform particle size were synthesized via a facile sol-gel method, and various sizes of NiO NPs (11, to 49 nm) were achieved by calcination at various temperatures (400, to 700 °C). X-ray diffraction (XRD) analysis revealed that increasing the calcination temperature increased the crystallite size. TEM observations and XRD analysis were used to determine the particle size of the NiO NPs. The field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) images showed flake-like morphologies, which consisted of interconnected nanoparticles with a porous channel. The magnetic properties of NiO NPs with different size were studied using vibrating sample magnetometer (VSM). The results suggested that the particle size plays an important role in magnetic property of NiO nanoparticles. | ||
