چکیده

Nanostructured Ni₂As₂O₇ semiconductor samples were synthesized by a solid state method among As₂O₃ and Ni(NO₃)_2.6H₂O raw materials at 650 °C (S₁) and 750 °C (S₂) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and Fourier-transform infrared (FTIR) spectroscopy. The Rietveld analysis showed that the obtained materials were crystallized well in the triclinic crystal structure with the space group P₁. The data of Rietveld analysis showed that the purity of the synthesized nanomaterials was increased by increasing the reaction temperature. The morphologies of the synthesized materials were studied by field emission scanning electron microscope (FESEM). It was found that the morphology of the obtained materials was changed from homogeneous sponge to particles and somewhat porous structure, by increasing the reaction temperature. Besides, the average particle sizes were increased considerably by increasing the reaction temperature. Ultraviolet-visible spectra analysis showed that the synthesized Ni₂As₂O₇ nanomaterials had strong light absorption in the ultraviolet light region. The direct optical band gap energies were 3.20, 3.90, 4.80 eV and 2.9, 3.40, 4.70 eV for S₁ and S₂, respectively. The data showed that the band gaps were decreased by increasing the reaction temperature that can be due to the increasing the crystallite sizes of the targets.
