Abstract
Zinc Sulphide thin films were grown by chemical spray pyrolysis. The influence of substrate temperature ST (250, 350 and 450°C) on structural and optical characterization is investigated. XRD Patterns of the synthesized film show the preferred orientation of (111) planes, confirming the Cubic structure of ZnS, The Grain size for pure of ZnS particle is about (19.05-32.80) nm with substrate temperature, whereas the strain (%) parameter decrease from 18.17 to 10.56. Surface topogrphy is studied by atomic force microscope (AFM). The grain size is observed in the area of (86.73), (78.74) and (77.58) nm for the substrate temperature (250, 350 and 300°C) respectively. band gap energy was set to decrease a bit with the increment of ST and was in area of 3.85–3.65 eV.
