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