Thin films of PVA/PEG and PVA/PEG/CdS nanocomposite liquid were prepared by spin coating that has a 132 nm thickness. The optical characteristics were examined., and the outcomes showed that the irradiation process led to an increase in the values of A and α decline in the values of T and Eg .The structural properties of XRD were studied and the results showed that the films prepared before and after irradiation were of the monoclinic type and that the irradiation process led to an rise in the G.S values and a decrease in the FWHM because the relationship between them is inverse. In addition, the Miller coefficients and the inter-crystalline plane distance were calculated. SEM was used to examine the produced thin film surfaces both before and after irradiation. The results showed that the irradiation process led to more homogeneity of the films, a reduction in crystalline defects on the film surfaces, and an increase in G.S. The XRD results and this outcome are in agreement.
