-> The nanocrystalline ZnO thin films were grown using the aqueous sol prepared by zinc acetate dehydrate and polyvinyl alcohol sPVAd. The concentrations of Zn2+ and PVA were 0.3 mol/l and 3 g/l, respectively. The sol was spincoated on Si s100d substrates and dried at 120 °C for six times, alternatively. Then, the films were heated at 600 °C for 30 min in a tubular furnace in air atmosphere
