Abstract

In this study, we report on preparation and characterizations of hybrid nano- TiO₂/ZnO using sol-gel spin coating techniques. The study involved of modification band-gap energy of Titanium dioxide (TiO₂> at different precursor molecular concentration of Zinc oxide (ZnO). The FESEM (Field emission scanning electron microscope) morphological characterize shows TiO₂ and ZnO particle produced at nanoscale size. The compositional of both particles confirmed using ED AX (Energy Disperse Analyzer X-ray) analysis. The XRD (X-Ray diffraction) characterize measured the structural properties of anatase and rutile for Ti02 as well as zincite for ZnO. We have found with increasing ZnO molecular concentration, the crystallite size, d were decreased until the optimum sample, ratio of 4 TiO₂: 1 ZnO, with value of 23.71 nm. For UV-VIS (Ultra-Violet/Visible Spectroscopy) measurement, we found the optical band-gap increased with increasing ZnO molecular concentration. The optical band-gap for optimum sample was 3.38 e.V represented this study has successfully improved the optical band-gap of Ti02. Hence, these results suggest for window solar tint film, coating mirror application and coating paint application.
