| Abstract | ||
| (CuS) thin films was prepared by Spray Pytolysis Method (SPM). Glass substrates with (1 * 2.6 * 7.6) cm were used at different temperature (180oC، 190oC ، 200oC) . The optical properties of the (CuS) films such as absorbance and transmittance have been analyzed using (UV – 1601) instrument at the wavelength range (200 – 1,100,00) nm. The optical band gab energy has been obtained from the plot between (αhv) and (hv) was ( 2.1 ) eV. The absorption spectra of the films showed that this compound is a direct band gap and this gap decrees with substrates temperatures . | ||
