Abstract
Thin films of pure copper oxide and doped copper oxide have been prepared bychemical spray pyrolysis. The films were doped with Manganese (Mn) by 2% & 4%
ratios. X-ray diffraction show that all prepared films have The two strong peaks of the
CuO films appear at 35.74o and 38.95o which correspond to diffraction from planes
(-111) and (111) respectively. The absorption coefficient was calculated from
transmission spectra range (450 – 950 nm) , the absorption coefficient increase by
doping, the allowed direct optical band gab energy has been evaluated from absorption
coefficient and the energy band gab increased by doping.
