چکیده
Abstract The physical properties of pure CuO and Pb doped thin films, deposited on glass substrates by a sol-gel method, were investigated. Structural analysis revealed the polycrystalline nature Pb:CuO composite films with monoclinic structure, crystallite size decreased ranged from 36.78 nm to around 21.5 nm. SEM images showed that doping concentration affects surface morphology composites. absorbance composites is higher than undoped films. optical band gap energies estimated 1.9 (pure), 2.17(5%) 2.74 (7%)eV, found energy (E g ) increases concentration. This blue shift due quantum confinement induced reduction in crystallites.
