Abstract

ZnO thin film has been synthesized using sol-gel spin coating method and reflux mixing technique process. The surfuctances are Zinc acetat dehydrate Zn(CH3COOH)2 2H2O, etanaol and diethanolamine (DEA) consecutively used as based material, solvent, and stabilizer. The molar ratio between DEA and ZnAc were 1:1. The ZnO film was grown on a glass substrates using spin coating technique with the speeds of consecutively 3000, 4000 and 5000 rpm, each for 30 seconds and calnination with pre-heating 300oC and post-heating 5000oC temperatures. The structural characterization results show the ZnO thin films are hexagonal and the smallest crystal size was 24.9 nm at the spinning speed of 5000 rpm. The optical characterizations show that the highest transmission is 52.6% at the spinning speed of 3000 rpm and the highest absorption is 1.277 at the spinning speed of 5000 rpm, and the smallest band gap of 3.13 eV at the spinning speed of 5000 rpm.
