The effect of doping with nickel oxide (NiO) on the structural and optical properties of vanadium oxide (V2O5) thin films prepared using the pulsed laser technique (PLD)
In this research ,pure thin vanadium oxide(V2O5) membranes impregnated with nickel oxide (NiO) were studied with different tarnishing ratios (X=0,2,4) % pulsed laser technology (PLD) was used in their preparation and annealing at a temperature of (450 °C) for an hour, and then their structural properties were studied using X-ray diffraction (XRD) the results showed that the prepared membranes are polycrystalline and of a rhombic Orthorhombic type (θ=27.889˚),the surface morphology of thin films was studied by field emission scanning electron microscope (FESEM), showed the change of the nanotube shape from nanotubes to spherical, and the analysis of (EDX) showed the containment of (V, Ni, O, Au), The optical properties were also studied using a (UV-Vis) spectrophotometer and the results showed that the prepared membranes have a reduced absorbency and absorption coefficient, and the energy gap increases from 2.23 eV to 2.55 eV. The material obtained is cost-effective and low-toxic, therefore it will be suitable for industrial use.
