Abstract
In this study we prepare Cu2O films by using plasma sputtering method on substrate from glass type Pyrex; we used system of dipole sputtering with magnetic field. We studied the optical and structural properties to Cu2O and we studied thermal annealing with 150◦C on optical and structural properties for prepared thin films with thickness 2000Ǻ for one hour. It showed that the thermal annealing leads to increase of optical energy gap. We used x-rays diffraction for diagnostic structure and nature thin film material. the results appear that the thin film is poly crystalline structure, the thermal annealing leads to drop of diffraction peaks and increase it edges that's means it become more uniformity as well as it consist of optical properties study about spectrum record for absorbance and transmission for the prepared thin films in visible region and ultraviolet for range of wave length 300-900 nm.
