the study of the structural properties of the prepared films The to study the effect of each of the irradiation with a CO2 And a beam of X-rays, as well as the effect of the doping process on the thin films of a (PVA) doped with aqueous zinc acetate. By 5%, the casting method was used to make it into a thin film It is deposited on 25.4 * 12.5 nm, and its thickness is approximately 380.42 nm. Then the samples were divided into two parts, the first exposed to a CO2 laser beam at a constant energy of 10 Watt and (3,6,9,12 sec), then it was exposed to X-rays for 1.5 h. And fixing the voltage of the X-ray f (5KV). The second section of the samples were exposed to X-rays for different periods of time (0.5, 1, 1.5, 2, 2.5 h) with a voltage of (5 KV). Then, t exposed to a (CO2) laser with a energy of 10 Watt and a fixed exposure time of 10 sec. The effect of irradiation in both cases studied on the optical and structural properties. The results of (XRD) that the mixture (PVA + Zn) showed that the crystalline nature is amorphous. For the purpose of studying the topography of the surfaces, the results of (AFM) showed a decrease in the particle size after irradiation of the mixture, and it was found that the effect of irradiation is more responsive in the case of (Laser + X-Ray)than of (X-Ray + laser).
