چکیده (انگلیسی):

Nickel oxide (NiO) nanocrystallites with a crystal size of around 54 nm have
been synthesized via the polymerized complex method. The synthesized precursor was
calcined at 873 K for 4 h to obtain the nickel oxide nanocrystallites. The XRD and
electron diffraction analysis results indicated that the calcined sample has a cubic structure
without any impurity phases. The FT-IR analysis result confirmed the formation of
NiO. The NiO nanocrystallites exhibited UV absorption below 2.76 eV and the estimated
direct band gap (Eg) of 3.06 eV. The Room temperature magnetization result revealed a
ferromagnetic-like behavior and a coercivity of 149 Oe. The ferromagnetic-like properties
are attributed to the lattice distortion and broken bond in the NiO nanocrystallites.
