Abstract :Nickel doped ZnO insert ignore into journalissuearticles values(NZO); and undoped ZnO thin films were deposited by wet chemical sol-gel spin coating method and their optical and structural properties have in detail been investigated by X-ray diffraction and optical absorption measurements to observe the effect of doping with different values of Ni molarity. The NZO and undoped ZnO thin films showed a growing trend along the c-axis perpendicular to the substrate surface. The strong insert ignore into journalissuearticles values(002); diffraction peaks at 2θ = 35.743°, 35.836°, 35.840° and 36.041° were observed to belong to samples undoped ZnO, NZO insert ignore into journalissuearticles values(0.25%);, NZO insert ignore into journalissuearticles values(0.50%); and NZO insert ignore into journalissuearticles values(0.75%); films, respectively. The band gap values have been calculated from the dependencies insert ignore into journalissuearticles values(2 vs hν); by extrapolating the straight lines to 2 = 0 and found as 3.2630 eV and 3.2820 eV for 0.75% NZO and undoped ZnO thin films, respectively.
