Preparation of nanohybrid PMMA/TiO2 hybrid was reported by using mixture sol-gel spin coating method. This studied involve modification band gap of TiO2 at different molar concentration of TTiB precursor. AFM image show TiO2 particles encapsulated with PMMA matrix. From UV-Vis spectroscope, we have found as increase of TTiB precursor molar concentration, optical band gap is 3.34 eV, increase in UV-range from 3.25 eV. This study suggested for improvement of optical band gap TiO2 coated glass.

ZnO thin films were prepared onto the glass substrates by the sol–gel spin coating method for various Zn concentrations and at different spin rates. The influence of concentration of zinc and spin rate on the structural and optical properties of the ZnO thin films were investigated. It was observed that the zinc concentration and spin rate influence the grain size and morphology of the ZnO thin films. The optical band gap energy was found to increase with decrease of Zn concentration and increase in spin speed. The photoluminescence peaks show green radiation at ~485 nm. It was also observed that the enrichment of zinc and variation in spin speed influence the intensity of luminescence peaks.
