Abstract

ABSTRACT:- The pure (MgO) membranes mixed with nickel (Ni) were prepared at the proportions of (0,1,3,5,7) using the method of pulsed laser deposition (PLD), as the deposition process was carried out on glass bases at room temperature, with a thickness of nm (200) where the effect of nickel mixing on the structural and optical properties was studied, as the results of X-ray diffraction showed that all the membranes that were prepared as having a cubic structure (Cubic) as well as within the structural characteristics The surface topography was studied with (AFM) and the results showed a decrease In the values of granular size, but through visual examinations, it was observed that the values of absorbency and absorption coefficient increase with increasing mixing ratio, while the optical energy gap decreases with increasing mixing with nickel  (7.79-3.43)eV.As for the values of sensitivity to gas, where they were increasing with temperature and the percentage of nickel addition, the highest percentage of sensitivity (42.12%) was obtained at the percentage of nickel addition (7%Ni).
