Özet

Cr dopant effect is investigated on MgO thin films which are grown by using successive ionic layer adsorption reaction (SILAR) technique. UV-Vis spectroscopy, XRD (X-ray diffraction), SEM (scanning electron microscope) measurements are performed to determine how Cr doping alters morphological, structural and optical properties of MgO nanostructures. UV-Vis spectroscopy measurements of plain MgO thin films and Cr added MgO thin films have shown that bandgap decreased with rising Cr additive from 4.00 eV to 3.45 eV. XRD measurements of samples have shown that all thin films were cubic structures and have planes of (200), and (220). The surface morphologies have presented that both pure MgO nanostructures and Cr added MgO nanostructures have nanowall formations and Cr dopant changed surface of MgO.
