Abstract: ZnOthin films were prepared onto the glass substrates by the sol–gel spin coating method for variousZnconcentrations and at different spin rates. The influence of concentration of zinc and spin rate on the structural and optical properties of theZnOthin films were investigated. It was observed that the zinc concentration and spin rate influence the grain size and morphology of theZnOthin films. The optical band gap energy was found to increase with decrease ofZnconcentration 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.
