ABSTRACT = {Using Sol-gel technology, nanocomposite CdS: ZnO thin films with an equal molar ratio of 
0.5 M on a glass substrate for water decontamination purposes. The ZnO doping ratios were 
(0, 1, 3, 5) vol. The ultrastructural, morphological, and optical properties of the prepared 
thin films were studied using X-ray diffraction (XRD), atomic force microscopy (AFM), 
and UV-vis spectra. The results indicated that the prepared nanostructured CdS: ZnO thin 
films contain uniformly spaced crystalline grains of both CdS and ZnO. The ZnO-doped 
selection ratio and uniform grain distribution produced outstanding photocatalytic and 
photocatalytic performance. With a red shift in the optical band gap of CdS, the UV-Vis 
transmittance spectrum of the nanocomposite shows behavior that extends almost uniformly 
throughout the entire UV-visible region according to the near-band edge emissions of CdS 
and CdS: ZnO, respectively. Last but not least, the photocatalytic activity of the 
photodegradation of methylene blue dye was investigated and the results indicated an 
enhanced efficiency of approximately 87% in 60 min, much higher than that of pristine CdS: 
ZnO as well as CdS. },
