Aluminum (Al) doped titanium dioxide thin film with different Al doping concentration (Al = 0 mol%, 1 mol%, 3 mol%, 5 mol% and 7 mol%) were deposited using solution spin coating technique and the effect of Al concentration on the structural, morphological and optical properties were examine. All samples were annealed at 450°C for 1 hour. XRD reveal that the films exhibits anatase crystal phase at (101) peak orientation. Based on the FESEM and AFM image it is found that, surface morphology of the film was significantly affected with different doping concentration. Al doped titanium dioxide with 3 mol% Al concentration shows the highest transmittance compared to others samples. Consequently, it is shown that different Al doping concentration plays vital roles in producing an optimum Al doped titanium dioxide thin films samples.
