| Abstract | ||
| This papar studies the optical feutures of the thin films of the pure CdO and that mixed with copper (3 ,5 , 7 ,10 %) which prepared by chemical spray pyrolysis were deposited on 500ºC glass substrates. and the amount of thickness (115nm). This papar studies the optical feutures through the spectrum trasnsmission (T) of the pure CdO films and that mixed with copper prepared in the range of wave lengh (290 – 1100). the stady finds that the pure CdO film trasnsmissin is high ,ranging between (80 -72) % in the visible area, it is found also that using mixing the trasnsmission of CdO film is reduced and the optical energy gap is also reduced the value the optical energy gap is also know which is (2.6 ev ) of the pure CdO As for the mixed, the value of the energy gap is reduced when the mixing in creasl (2.56 , 2.5 2.46 , 2.4 ev) for the percentages (3 ,5,7,10) % consequently. No indirect trasnsmission , in all the prepared films is noticed .The rest of optical constant factors were calculated as funactions the fotpn energy, which include (absorption coefficient, extinction coefficient) . | ||
