The presented research aims to study the influence of sulfur incorporation on the optical, morphological, structural and electrical properties of chemically deposited zinc selenide thin films. The structural analysis reveals a peak shift of 0.47° of 2θ angle as the sulfur incorporation level increased from x = 0 (0 %) to x = 0.3 (15 %). The EDAX study shows that pure zinc selenide films are rich in selenium. With an increase in sulfur incorporation levels there is a continuous fall in selenium content. There is a significant reduction in variations in the range of grain sizes observed in SEM micrographs as the incorporation level increases. The transmittance is found to be higher in sulfur incorporated samples. The band gap energy is found to be increased from 2.63 to 3.17 eV with a rise in the sulfur incorporation level. An increase in the concentration of sulfur causes a rise in resistivity from 106 to 107 Ω×cm.
