Abstract

Copper oxide CuO thin films were deposited on glass substrates using chemical bath deposition technique. The films’ growth was based on the decomposition of cupric sulphate in the presence of sodium hydroxide with EDTA disodium salt (CH2N(CH2COOH)CH2COONa)22H2O) acting as complexing agent. Optical and morphological investigations were also performed. The films were found to have strong absorption of approximately 0.87 at wavelength range of 300-320nm. The optical absorbance generally reduced with increase in wavelength. The optical band gap of the deposited film was found to be 1.7eV.
